Ay, what a topic! I won't pass by.
The problem raised by Tatyana is truly pressing. Electronic kitchen scales do not show tenths of grams; between adjacent values of 1 and 2 grams the difference in weight is 100%.
A couple more ways to measure small amounts of dry fertilizer.
Volumetric weighing
With all the variety of thimbles, the average volume of a thimble has remained unchanged for centuries - about 2 milliliters:
Measuring the volume of a thimble
If you have some kind of non-standard thimble, then:
- set to zero
- pour 10 thimbles into a cup
- Divide the scale reading by 10 to get the volume of the thimble (1 milliliter of water = 1 gram of water).
If you don’t have scales on your household, fill a 100 or 500 gram jar with your thimble. And divide the volume by the number of thimble portions used. This will give you the volume of a non-standard thimble.
Or use a used syringe to draw in the water that fits into the thimble - the divisions on the syringe will show how much volume it contains.
Theoretical rationale for volumetric weighing
It is necessary to make a reservation that not every fertilizer has an equality of 1 milliliter of volume to one gram of weight. Therefore, Tatyana indicated fertilizers for which this equality is observed.
Fertilizers often have a lower density than water. But for violets, some lack of fertilizer is not critical, especially taking into account the recommendations for violets to dilute standard fertilizers by half. Therefore, volumetric measurement of fertilizers is quite appropriate in caring for violets, even if the density of the fertilizer is unknown.
After using the thimble, be sure to rinse it, fertilizer dust may not be the best reagent for your finger.
Pirate way to determine small quantities
Place the contents of the fertilizer bag on a piece of paper. The weight is written on the bag. By eye, move some of the fertilizer to the side so that in a large pile there remains fertilizer to one of the powers of two (2, 4, 8, 16, 32, 64,... grams).
Divide the large pile in half. Divide each half in half again. Divide the quarters in half too. Eights are also halved. At some point you will end up with many, many small piles of fertilizer, each containing about 1 gram. Pack each pile in a small paper bag and use as needed for the health of your violets.
Using the same method, you can measure, for example, 1/8 of a gram from 1 gram of potent fertilizers.
Option. If you have a large bag of fertilizer and a kitchen scale, you can measure, for example, 16 grams and package it as suggested.
Historical excursion
In countries where there were many pirates at one time, there is still a running joke:
Question: How many pirates can there be on a pirate ship?
Answer: 2, 4, 8, 16, 32, 64, 128,... Otherwise, you will have to shoot the extra ones during a fair division of the spoils.
Jokes aside, the pirates were great at dividing their booty into any equal number of parts, and everyone considered the division fair.
For this there was a special way of sharing, which was called pirate. In its simplest form (2 pirates), one pirate divides the booty as he sees fit into 2 equal parts. And the other chooses the part that seems larger to him. Questions about fairness do not arise for either side.
For a larger number of people, division follows a similar scheme in several stages - first large groups of pirates divide the loot, then within the group the pirates are split into small groups and continue to divide small groups among themselves, and so on until the entire large pile of loot is divided between many pairs of pirates. Considering that the pirate life was short, everyone was in plain sight, and during the capture of ships, pirates often saved each other’s lives, they often trusted their fellow pirates, who were better familiar with the value of the loot in the colonial markets, to divide/choose their share.
IN English speaking countries The medieval “pirate” is still one of the most favorite masquerade images for children:
Measuring small amounts of liquid fertilizer
I will add that you can also conveniently measure liquid fertilizers from bottles with a syringe.
And with a pipette you can measure out a very small amount of fertilizer. Don't know how much one drop from your pipette weighs?
- place an empty cup on the kitchen scale
- set to zero
- pour 100 drops into a cup
- Divide the scale reading by 100 to get the volume of the droplet (1 milliliter of water = 1 gram of water).
Similarly, you can measure how much a droplet weighs from a jar of Corvalol and use it as a container for storing liquid fertilizer.
The sizes of droplets from different pipettes and different jars strongly depend on their parameters, so it is better not to use the data obtained for one pipette or jar for others.
Hello, dear readers! Sooner or later, any gardener is faced with plant diseases, crop pests and soil depletion. Constant crop rotation and the use of chemicals have a detrimental effect on the fertile layer, and we are forced to constantly fertilize the soil and feed the plants. Because of this, the market for artificial fertilizers is constantly searching for an alternative remedy, unaware of, and perhaps ignoring, the one thing that is most true.
We're talking about . It is used in everyday life, in nuclear reactors, in medicine, in jewelry, in various production. Among summer residents, boric acid is no less popular and a common question still remains: is it possible to spray tomatoes with boric acid?
What are the benefits of boric acid for tomatoes?
Boron is important element, very necessary for tomatoes. It promotes the rapid supply of useful elements to the plant from the soil and stimulates the growth and formation of the ovary.
A solution of boric acid can be used both for watering tomatoes and for spraying. The second method is more effective, since plants absorb more intensively nutrients through the foliage.
The addition of liquid boric acid as a top dressing helps wild flowering tomatoes and allows you to preserve them on the bush, form ovaries, and protect the fruits from.
Summer residents who regularly use boric acid solution as a fertilizer note that the ripening of berries increases by 20-25%. In addition, they are born with increased sugar content, which significantly affects the improvement of taste.
Plus, treating with this product will help protect tomatoes from harmful agents, and we’ll find out how to do this correctly later.
Timely use of boric acid
The product can be used throughout the season, but in order for boric acid to benefit the tomatoes and not harm them, it is recommended to fertilize them strictly at a certain time.
These periods can be divided into three parts:
Just before flowering, when the buds form
During intensive flowering of most plants
During the period of active fruiting
What is important is how many times, in what quantity and at what time the feeding took place. By observing these conditions, boric acid will become your friend and assistant in the garden.
You can feed tomatoes at a very early stage of development, but after that the bushes are not fertilized until the buds appear, for fear of an excess of microelements.
Spraying is not recommended during active flowering. You should wait until the next bud set and only then fertilize.
Repeated treatment of tomatoes with boric acid is usually carried out no earlier than every week, or even once every 10 days. And if after the first feeding the tomatoes become worse, then stop spraying with boric acid completely and do not use it unless absolutely necessary. This is also possible, and plants sometimes react individually to a particular environment. This can be affected by both precipitation and other fertilizers that are incompatible with boric acid.
Proper Use of Boric Acid
The process of applying boron to tomatoes is simple. For the solution you need to take 1 gram of boric acid, dissolve it in a small amount hot water, and then bring it to a volume of one liter with plain water. This measure is enough for a square meter.
There are other dosages of this product, for example, to preserve the ovary: dissolve approximately 7-8 grams of boric acid with 10 liters of water and spray the plants so that the leaves and ovaries are well moistened with the solution.
And to protect against late blight, pour a teaspoon of the substance into a ten-liter bucket and dissolve it with water to the full volume. We treat the bushes with the resulting liquid in the second half of June, and a week later again, only with a weak solution. After potassium permanganate, after the same period of time, spray the tomatoes with a weak solution of iodine.
By the way, additional and especially effective means ordinary brilliant green is considered to be from late blight,
40 drops of which per bucket of water will reliably protect tomatoes from fungus. Together with brilliant green, trichopolum is an excellent ally in the fight against this infection.
One Trichopolum tablet dissolved in a liter of water will cope with this task in 2 sprays with a gap of 2 weeks. Trichopolum is such a bitter drug that not a single harmful insect will crawl to your beds. And the antibacterial properties of brilliant green will save plants from fungus.
Any spraying of tomatoes should be carried out on cloudy days or in the morning (evening). If tomatoes grow in open ground, and not in a greenhouse, then take into account the prospect of precipitation and do not spray the plants into the wind, and the spray bottle should have a fine spray.
It is very important to maintain proportions and it is better to not get enough sleep than to overdo it, because an excess of boron can cause irreparable harm to tomatoes. For convenience and to guarantee the correct result, you can purchase a ready-made solution of boric acid at the pharmacy and bring it to the required volume by diluting it with water.
Thanks to the correct use of boric acid, you can effectively fertilize your plants and protect them from danger, resulting in a rich and environmentally friendly harvest.
By the way, about a rich harvest...
Before you plunge into gardening chores on your site, you can plan and put into practice all your plans for the season using a computer simulator for summer residents "Rich Harvest".
We learn from our mistakes on the computer and do not torment the plants with dangerous experiments in the garden. By exercising on the “Rich Harvest” simulator for summer residents, you can understand what will happen if you use fertilizer incorrectly, find out what the consequences and achievements may be.

How to properly use boric acid in a suburban area, is it possible to spray flowers with boric acid, as well as other useful information Read about this essential microelement in our material.
The range of applications of boric acid is quite wide. In medicine, it acts as an antiseptic, in photography - as a component of the developer. Boric acid is used to get rid of cockroaches, produce glass, and use it in nuclear reactors and jewelry. But we are primarily interested in how boric acid is useful for plants and why it is needed in the country.
Signs of boron deficiency
Boron is an important trace element necessary for normal plant development. It has a positive effect on metabolism, promotes the production of chlorophyll, and helps roots “breathe.” The effects of boron starvation are easy to notice in dry weather. To identify boron deficiency, inspect the plant, paying special attention to young parts.
The plant urgently needs treatment with boric acid if the following “alarm signals” are detected:
- chlorotic spots on young foliage, leaf veins turn yellow;
- leaves become smaller, curl and fall off;
- apical buds inhibit growth, lateral buds, on the contrary, enhance;
- the plant blooms weakly, the fruits set poorly;
- fruit deformation (ugly shape);
- in pome crops, suberization of fruits is observed;
- death of bark on shoots or entire tops.
Plant growth is suppressed, and if measures are not taken in time, you may lose the harvest. But you shouldn’t overuse fertilizer: with an excess of boron, although plant fruits ripen faster, they are stored worse, and the leaves run the risk of getting burned.
How to use boric acid?
Boric acid is used for seed treatment and plant nutrition. To speed up seed germination, boric acid is diluted in a proportion of 2 g per 10 liters of water, the seeds are placed in a fabric bag and immersed in the solution for a day.
Seeds of zucchini, cucumbers and cabbage are soaked in boron solution for 12 hours.
Depending on the extent to which a particular crop needs boron, plants are divided into 3 groups:
- Minor degree: herbs, legumes, strawberries, potatoes (we’ll talk about the last two crops separately).
- Average degree: most green and vegetable crops, stone fruit trees, berry bushes.
- High degree : cabbage, pome trees, beets.
Plants first group, as a rule, they are fed only in case of boron starvation (pre-sowing application of fertilizer to the soil is also appropriate).
Potatoes and garden strawberries (strawberries) are among the group of plants that have little need for boron, and yet a lack of the microelement can significantly affect these crops. At the slightest sign of boron starvation in potatoes, watering the plants with boric acid will help (6 g of fertilizer per 10 liters of water, this amount of solution is enough to treat 10 sq.m.). Read about strawberries below.
For crops second group Foliar fertilizing with boric acid (2 g per 10 liters of water) twice per season is suitable: the first time - at the bud opening stage, and then 5-7 days later (ovary formation stage).
Third group plants need boron fertilizing more than others. In areas with fertile soil, crops are traditionally sprayed with a 0.01% solution, in areas with less fertile soil - 0.02%. For poor soils, the concentration should be increased to 0.05-0.1% (5-10 g of boric acid per 10 liters of water, consumption 1 liter per 1 sq.m). The application schedule for most crops is the same as for the second group.
Pome fruits are treated with boric acid three times: at the beginning of budding, at the beginning of flowering, and after the flowers fall off, when the fruits begin to fill.
Boric acid: instructions for use
Boron does not dissolve in cold water, therefore, to prepare the solution, the water must be heated. In order not to heat 10 liters of water (which, you see, is not very convenient), there is a little trick. A solution of boric acid is prepared as follows:
- the required amount of the substance is dissolved in 1 liter of hot water (70-80°);
- the resulting “mother” solution is cooled and water is added to it to 10 liters.
How many grams of boric acid are in a teaspoon?
Typically, a sachet contains 10 g of boric acid, and a standard teaspoon holds half of the entire serving - 5 g. Be careful when working with boron and, if possible, use a spoon that is not suitable for food (or wash the spoon thoroughly after measuring substance).
How much is 1 gram of boric acid?
As they say, we asked - we answer. To measure 1 g of suspension, lay a sheet of paper on the table and carefully pour 1 tsp onto it. boric acid. Then, using, for example, a knife or a flat stick, divide the powder into 5 equal parts. Leave one part (this is 1 g), put the rest in a bag.
How to feed plants with boric acid
In most cases, spraying with boric acid is used. "Three whales" foliar feeding:
- evening time;
- warm cloudy weather;
- fine spray.
When spraying a plant, do not get carried away: “dew” on the leaves and branches is a sign to stop. Dripping should not be allowed.
Watering the soil with a solution of boric acid is acceptable for emergency assistance to the plant (this mainly applies to potatoes and strawberries). You need to water the plant from a watering can and strictly at the root, so that the drops do not fall on the plant itself.
Boron suspension in its pure form is not used in the garden - there is a risk of burning the plant or, conversely, “losing” the fertilizer in the soil.
Boric acid for tomatoes (tomatoes)
Typically, tomatoes are fed with boric acid solution three times. The first time - before flowering, when the buds have already formed (1 g of powder per 10 liters of water, consumption 1 liter per 1 sq.m.). Then boric acid for the ovary is applied during flowering (no less than 10 days after the first, the concentration is the same), and the final feeding occurs at the fruiting stage.
At the very beginning of the fruiting phase, tomatoes can be fed with a mixture that includes ash, iodine and boric acid. The feeding is prepared as follows:
- dilute 1.5-2 liters in 5 liters of boiling water wood ash and 10 g (1 sachet) of boric acid, mix thoroughly, cool, then add water to the solution to make 10 liters;
- pour 1 bottle of iodine into the solution and leave the mixture to infuse for a day;
- Before use, dilute 1 liter of infusion in 10 liters of water to obtain a working solution.
Application rate - 1 liter per bush. Such fertilizing will not only speed up fruiting, but also increase the resistance of tomatoes to late blight.
Boric acid for cucumbers
Cucumbers are fed according to the same scheme as tomatoes, the solution concentration is 0.05% (5 g of boric acid per 10 liters of water). Boron improves the taste of cucumbers, stimulates the formation of ovaries and the development of fruits. This microelement also improves frost and drought resistance of plants, and also helps strengthen the root system of cucumbers.
Fertilizing strawberries with boric acid
The first feeding is carried out early spring: 1 g of boric acid is dissolved in 10 liters of water (previously filled with a small amount of hot water) and 1 g of potassium permanganate, and the strawberry beds are watered, using the solution for 30-40 bushes. The second feeding is carried out before flowering, at the stage of bud extension. Plants are sprayed with a mixture prepared according to this recipe:
- prepare an extract from wood ash (pour 1 glass of ash into 1 liter of boiling water, stir and leave for 24 hours, then strain the infusion);
- to 10 liters of water add 2 g of boric acid (previously dissolved in a small amount of hot water), ash extract and 2 g of potassium permanganate.
Consumption - 0.3-0.5 l per 1 bush. This solution is also used for obvious signs lack of boron in strawberries.
Boric acid for flowering
Boron is indispensable not only in the vegetable garden, but also in the flower garden. Ornamental plants also fed with a solution of boric acid. The optimal concentration for spraying most types of flowers is 0.5 g per 10 liters of water. For root feeding, prepare a “stronger” solution: 1-2 g per 10 liters of water.
Boric acid for ants (against ants)
Boric acid will help cope with ants on the site. Here are a few bait recipes:
- Grind 0.5 tsp. boric acid and 2 egg yolks. Roll the mixture into small balls (no larger than a pea) and place along the ant trails.
- Grind 3 boiled potatoes (in their jackets) with 3 egg yolks. Add 1 tsp. sugar and 10 g of boric acid, mix. Roll balls and place them in ant habitats.
- Mix 2 tbsp. glycerin and 1 tbsp. water, add 1.5 tbsp. sugar, 1/3 tsp. boric acid and 1 tsp. honey Form into balls.
dry ingredients(loose, solid products) are usually indicated in grams or measured in glasses, teaspoons or tablespoons. Well, everything is clear with grams.
If you have a kitchen scale, then you probably know what to do. If there are no scales, then we need to somehow convert our grams into glasses or spoons, based on how much of a particular product is required. It is more convenient to measure larger quantities in glasses. This is where it will help us food weights table measuring cup faceted no need compact. Volume teaspoon should be 5 ml, and dining room
Quantities liquid products
If you don't have a cut glass in your kitchen, use a measuring glass. Look for the 200 and 250 ml marks. For clarity, they can be emphasized with a bright marker. If you need a cup of flour, add it to the bright line. Of course, if the required amount of flour is a multiple of 200 grams, then it is more convenient to use a measuring cup (flour scale). At the same time, spoon the flour into the glass, rather than scoop it up. IN the latter case voids may form. It is more convenient to measure small amounts of flour with a tablespoon. A spoonful of flour is a heaped spoonful. Flour should be sifted only after the amount required for the recipe has been measured, since sifted flour does not fit so tightly.

Potassium permanganate (or potassium permanganate) is used in everyday life for various purposes: as a remedy in a home medicine cabinet, for removing stains from fabrics and for cleaning dishes. In this case, it is not the potassium permanganate crystals themselves that are used, but a water-based solution.
Depending on the intended purpose (oral intake, external skin treatment, household use), a solution of potassium permanganate requires different concentrations: as a rule, from 0.1% to 5%. A stronger solution (as well as contact with crystals on the skin, especially in combination with moisture) can cause severe irritation and even burns.

Preparation
In order to make a 5% solution of potassium permanganate, it is worth considering that:
- When working with potassium permanganate, it is better to protect your hands with gloves to avoid contact of the concentrated substance with the skin;
- To prepare the solution, it is better to use clean (boiled) water, warm (with a temperature of about 35-40 degrees);
- To get a 5% solution, you need to pour 5 grams of potassium permanganate into 100 ml of water. Usually crystals are sold in containers of 3 g - this dose will require 60 ml of water;
- After the crystals have dissolved, strain the solution to avoid getting any remaining crystals on your skin. For straining, you can use gauze folded in several layers;
- The finished 5% solution should be saturated purple. Used for external use when refrigerated (up to room temperature) form.
If the solution is made with distilled water, it can be stored in a dark place for up to six months.
Usage
A 5% solution of potassium permanganate is considered quite strong. However, it has also found its area of application. Most often, it acts as a potent antiseptic for serious skin lesions. This solution is used:
- For treatment (cauterization) of deep wounds;
- For disinfection and speedy healing of bedsores;
- For healing the navel in newborns, if less potent drugs (brilliant green, hydrogen peroxide, etc.) have not helped;
- For washing wounds from the bites of some poisonous spiders or snakes;
- For lotions for severe thermal burns.
Such a strong solution cannot be used internally - this can cause damage to the mucous membranes of internal organs. Potassium permanganate should be on hand in your home (and travel) first aid kit.
Neutralization
If crystals of potassium permanganate do get on the skin, or a strong solution of potassium permanganate is drunk, its oxidizing effect must be neutralized. To do this you need:
- Drink or apply milk or the whites of raw fresh eggs to the skin lesions;
- Rinse the stomach (if taking potassium permanganate orally). Warm water with crushed activated carbon is used;
- Consult a doctor: both in case of external and internal burns. If taken orally, you will need to adhere to a strict diet for some time.

When we find a new recipe for ourselves, on the Internet or a new cookbook, or perhaps a friend shared it, then first of all we pay attention to the products needed for cooking, and especially to their proportions. Quantities dry ingredients(loose, solid products) are usually indicated in grams or measured in glasses, teaspoons or tablespoons. Well, everything is clear with grams. If you have a kitchen scale, then you probably know what to do. If there are no scales, then we need to somehow convert our grams into glasses or spoons, based on how much of a particular product is required. It is more convenient to measure larger quantities in glasses. This is where it will help us food weights table. It will also be needed for reverse recalculation, when it is more convenient for us to measure all quantities using scales, rather than dirty glasses and spoons. But it is important to remember that in recipes adapted for Russia, a glass does not mean measuring cup(minimum volume - 300 ml), and regular faceted(volume up to the marks - 200 ml, to the edges - 250 ml). In this case, the glass must be filled exactly to the line where the edges end, no need compact. Volume teaspoon should be 5 ml, and dining room- 18 ml. We scoop dry products with a heaped spoon.
In foreign culinary literature, quantities are measured not in glasses, but in cups. But this doesn’t really change anything, since a cup is the same glass, filled to the brim - the same 250 ml. If you often come across recipes with "cups" instead of "glasses", then you will find the following information useful.
In this case, we use a measuring cup, or buy ourselves a special set of measuring spoons. Fortunately, these are on sale.
Quantities liquid products indicated either in ml or in glasses, spoons. Sometimes the value is indicated in grams. If glasses are indicated - take a faceted glass, spoons are indicated - use them, milliliters are indicated - take a measuring cup, grams are indicated - use scales, or use the table to determine how many glasses or spoons are needed. And again, the table of food weights comes to our aid. Liquid foods should fill spoons to the brim. Scoop viscous products with a heaped spoon.
If you don't have a cut glass in your kitchen, use a measuring glass. Look for the 200 and 250 ml marks. For clarity, they can be emphasized with a bright marker. If you need a cup of flour, add it to the bright line. Of course, if the required amount of flour is a multiple of 200 grams, then it is more convenient to use a measuring cup (flour scale). At the same time, spoon the flour into the glass, rather than scoop it up. In the latter case, voids may form. It is more convenient to measure small amounts of flour with a tablespoon. A spoonful of flour is a heaped spoonful.
How to weigh 1 gram without precise scales
Flour should be sifted only after the amount required for the recipe has been measured, since sifted flour does not fit so tightly.
How to measure the right amount of product is up to you to decide. We hope our summary table will help you when preparing your meals. For your convenience, the products in the table are arranged in alphabetical order. Some foods are grouped (legumes, cereals, nuts, etc.). The table indicates how many grams the product is contained in a certain volume.

Instructions on how to measure 2 grams (g, g) of water - this is how many drops, SEE TABLE 1, we measure dosages in grams, how to calculate the number of drops of water in 2 grams (g, g).
There is an approximate way to measure 2 grams (grams, g) of water in drops, without weighing on a scale. Technically, measuring grams of water in drops is not difficult - you just need to count the required number of drops. To do this we need to know the ratio of grams to drops. More precisely, we need to determine the weight (mass) of 1 drop of water, which is known background information, which we use to determine servings by weight in grams. You do not need to repeat the calculations yourself; just look at our instructions - “how to measure at home”, located below the text of the article. How many drops in 2 g (g, grams) of water are indicated in the table. Do not forget that the method of measuring in drops is not only an approximate option for determining weight in grams, since it depends on the shape of the hole in the vessel, but also works best only when measuring 2 grams (grams, g) of distilled water. The more impurities, salts, and additives in a liquid, the less accurate the measurement method turns out to be. Method for measuring 2 g (g, grams) of water in drops, has its own methodological features for performing measurements. When used by professionals, for example: used in laboratory and pharmaceutical settings. What are the features of the laboratory technique for determining the weight of water in grams without scales? For example, pharmacists measure grams (g, g) in drops using a special tool - a dispenser. In the pharmaceutical reference book, where the ratio of ml, grams and drops is considered in the most detail, accurately and correctly, this does not refer to any drops, but specifically to those obtained when using a dispenser. Your own water droplets will likely vary slightly in size, volume and weight (mass). How many drops of water are in 2 grams (g, g) is not considered an exact value also because the method is based on a statistical generalization of the results of experimental studies (measurements). In each specific measurement, the counted number of drops is different, but always close to the average value indicated in Table 1.
How to weigh Altai medicinal herbs, roots and mumiyo
How to measure 2 grams (g, grams) of water - how many ml (milliliters). In grams we measure the weight (mass) of a liquid, and in milliliters we determine the volume.
How to measure a portion of water in grams, for example, measure or count 2 g (g, grams) using milliliters for calculation? For water, just for it and only, there is a very convenient ratio of the weight (mass) of the liquid in grams (g, g) and volume in milliliters. The number of ml and the number of grams are the same. It is worth clarifying that for other liquids this ratio of weight in grams and volume in milliliters will be different. Moreover, if we are not dealing with a distillate, then number of milliliters (ml) in 2 grams of water will differ from the indicated grams in Table 1. For domestic conditions, when we need approximate calculations of the amount of g of water, dosage in grams or approximate portion in g, a completely correct option is to use reference data on the number of milliliters of water (ml) in 2 g of liquid from table 1.
It is convenient to measure some portions of water in grams with a syringe or dispenser with a scale in cubic centimeters (cm3, cubes, cubes). Questions may arise with Converting cubic centimeters of water to grams or milliliters. Milliliters (ml), like cubic centimeters (cm3), are units of volume measurement, with the difference that the former are used to measure volumes of liquids only, while cubic centimeters are more universal units and are used to determine the volumes of both liquids and solids , bulk materials, gases, vapors and so on. In general, converting milliliters of liquid to cubic centimeters is a relatively simple mathematical problem. However, without constant practice, converting or converting into cubic centimeters (cm3) can cause some difficulties for any normal person. Therefore, we indicated in the table how many centimeters of cubic water are in 2 g (grams, g) a separate column. By the way, for water, the number of cubic centimeters and the number of milliliters turns out to be the same, which is useful to simply remember and use at home when measuring portions.
How to measure 2 grams (grams, g) of water - this is how many tablespoons and how many teaspoons. The instructions will help you measure weight in grams and determine the mass of a portion of water without weighing it on a scale.
It is quite possible that you will find it convenient way to measure 2 g (g) of liquid with a spoon, based on the use of a tablespoon or teaspoon when measuring weight, calculating quantities, or determining servings. How to measure 2 grams (g) of liquid with a spoon, in our case, is based on measuring the number (how many) milliliters. And between milliliters and units of weight (g, g) there is a mathematical connection that allows you to recalculate the units. Spoons, both tablespoons and teaspoons, although their capacity is considered standard, cannot be considered precise measuring instruments for measuring volume in milliliters. Still, spoons are primarily cutlery. However, at home, tablespoons and tea spoons are actively used to measure not only volumes, but also weight (mass). At least, the question: how many tablespoons and teaspoons arises quite often. Naturally, we could not “bypass” it by indicating in the table a separate category (column) for tablespoons and teaspoons. The number of teaspoons is given by the first digit, and the number of tablespoons by the second digit, separated by a slash. It should be noted that measuring portions of water with spoons is relatively convenient and the inevitable errors of this method turn out to be relatively small. This means small compared to powders and bulk materials. Water in a spoon, thanks to her physical properties, does not create a big slide. Although there is a small mound in a spoonful of water, its size is safely neglected when measuring milliliters (ml) with a tablespoon or teaspoon. There is another type of spoon - dessert spoon, they are larger in size than teaspoons, but smaller than tablespoons.
Liquid volume units such as ml are used for small quantities of water. Large volumes are measured in liters and cubes (cubic meters, cubic meters, m3). There is a standard correspondence between milliliters, liters and cubic meters used in calculating the volume of liquid substances. We do not list the number of cubes (cubic meters, cubic meters, m3) in the table in a separate column. The calculation, if it is necessary to convert liters (l) to cubes (m3), can be easily done independently using the ratio: one cubic meter of any substance always holds 1000 liters (l). For 2 grams (g, grams) of water, we indicated in the table how many liters (l) it is - quantity. That is, it is not necessary to convert or convert milliliters to liters; you can find out the number of liters (l) from the reference data in the instructions (see Table 1).
How to measure 2 grams (grams, g) of water - this is how many standard glasses with a capacity of 250 milliliters and how many standard faceted glasses with a capacity of 200 ml.
We measure water at home not only with drops, tablespoons and teaspoons. When the volume or weight of water we need becomes large enough, it becomes more convenient to measure the amount of liquid with other kitchen tools. For example: measure in cups and glasses. You can use cups to measure liquids if you know their capacity. Manufacturers of tableware, as a rule, do not try to make cups standard in volume. But for glass glasses it is customary to maintain a standard container. Glass glasses are often called that - standard, standard tableware. There are two types of standard glass glasses: thin-walled and faceted glasses. They vary slightly in shape and appearance. However, for measuring portions, it is not the shape that is more important, but the fact that the glasses have different capacities. Not everyone knows that a standard thin-walled glass is 50 ml (milliliters) larger in volume than a faceted glass. To be precise, a standard thin-walled glass has a volume of 250 ml, and the capacity of a standard faceted glass is 200 ml. 2 grams (g, grams) of water in glasses see table 1.
Table 1. How to measure 2 g (g) of water - how many drops, how many tablespoons, teaspoons, cubic centimeters (cm3), how many liters, milliliters (ml) and glasses (with a capacity of 200, 250 ml).
Volumetric measures of berries and fruits
Volumetric measures of berries and fruits often needed when preparing various delicacies from them: preserves, marmalade, marmalade. After all, you don’t always have scales at hand, and this product is often perishable. Well, if you don’t have a measuring cup, you can replace it with a simple half-liter jar. It contains two 250 gram glasses. Accordingly, if you divide the jar in half (for example, with a wax chalk or marker), it will be 1 measuring cup.

How to weigh without scales
You don’t always have measuring cups and scales at hand, but you need to weigh your food. Therefore, you can use the secrets of our grandmothers.
To do this, take two pans of different sizes.
How to measure the right amount without scales (with spoons and glasses)
An object whose mass is known is usually placed in a smaller pan, for example a pack of salt (1 kg).
The pan with the item is lowered into a large pan filled with water.
The water level rises, we mark it with tape or wax chalk.
Then we remove the salt (or other item) from the pan and place the mass of the product that we need to find out.
The water rising to the marked level will show that their mass is equal.
A lot of food in a spoon.
We often think about how many calories we consume per day.
Many also have a table of caloric content of foods.
But how can you measure the mass of the food itself if you don’t have scales?
You can use in a simple way- find out the mass of food in an ordinary tablespoon.
After all, most of us use this device, and of course a fork.
But for the sake of the purity of the experiment, we will neglect the rules of etiquette and use a spoon for 2-3 days.
1 tablespoon contains:
Vinaigrette or salad - 30 g
Meat pieces - 25 g
Garnish - 35 g ( stewed cabbage, mashed potatoes, rice or buckwheat porridge, pasta)
Soup - 20-25 g (depending on its thickness)
Slicing wheat or rye bread 1 cm thick - 50 g
Sliced white loaf 1 cm thick - 15 g

How many grams are in a teaspoon?
To measure small amounts of food, it is recommended to use a teaspoon. 1 standard size teaspoon holds only 5 ml of water.
How to measure 1 g of dry fertilizer
It is water that is taken as the basis for measurement. Due to the huge variety of teaspoons of different volumes, before starting measurements, it is necessary to measure the volume of a teaspoon with a measuring cup or beaker. Finding out how many grams are in a teaspoon of a particular product is not at all difficult. You just need to scoop up a heaping amount of the required ingredient. It is possible to measure sugar and salt, tea and coffee, as well as butter, flour and even honey. A teaspoon is especially often used to measure soda, vinegar or yeast, since a significant deviation of these ingredients in dishes, as a rule, is simply unacceptable.

So, you want to find out how many grams of boric acid are in 1 (one) teaspoon, convert teaspoons to g, gr. We will help you measure a portion of the product in grams without scales using a teaspoon . You, dear visitor to our site, only need to select the degree of filling of the spoon. What options might there be? See photo. It turns out that not everything is so simple. After all, we do not use a teaspoon for its intended purpose, as a cutlery, but are trying to use it as a measuring device that allows us to measure a certain volume. This is where we run into some problems. Depending on your “courage”, you can scoop up a very different amount with a spoon. For example:
- Not quite complete- weight is indicated in TABLE: 4 ml
- No slide- weight is indicated in TABLE: 5 ml
- Little slide- weight is indicated in TABLE: 6 ml
- Middle slide- weight is indicated in TABLE: 7 ml
- Big slide- weight is indicated in TABLE: 9 ml
- o-o-very big slide, the maximum of reasonable ones- weight is indicated in TABLE: 10 - 11 ml
- A cut glass tumbler is smallest glass volume 200 ml(two hundred milliliters and two hundred cubic centimeters).
- A standard glass is large glass volume 250 ml(two hundred and fifty milliliters and two hundred and fifty cubic centimeters).
- A measuring cup is"neither this nor that", more than faceted, but less than standard glass, its volume is equal to 240 ml(two hundred and forty milliliters and two hundred and forty cubic centimeters).
- Teahouse is smallest volume 5 ml. But 5 milliliters are obtained only when NO SLIDE AT ALL, but full.
- The dining room is large volume 15 ml. But 15 milliliters are obtained only when NO SLIDE AT ALL, but full.
- Dessert is"neither this nor that", more than a tea room, but less than a dining room, volume 10 ml. However, as you already guessed, 10 milliliters will be obtained if NO SLIDE AT ALL, but full.
The best way to find out your weight or how to measure a portion of boric acid in grams than direct weighing on precise scales has not yet been invented. An irrefutable, fundamental, sad and concrete fact. However, in practice, weighing small portions, even if you have scales in your kitchen (this happens by accident, I saw it myself once), is such a “headache” that a normal person will agree to get involved with weighing only “on pain of death” (figurative expression, in fact, no one has died for this reason yet). Only a very pedantic and meticulous (what a word!) person can force himself to voluntarily and not force himself to mess with the scales in order to measure out a little of the product according to the recipe. A true enthusiast of his craft, a “fanatic” of accurately measuring portions in grams.
If we put aside a certain touch of humor, without which it would be completely depressing to communicate, then the problem, by the way, is far from being a “kitchen problem”. In production, when receiving, packaging, selling, processing, storing and transporting, professionals also try to avoid weighing on scales. This procedure objectively complicates the organizational structure and incredibly effectively extends the time of any technological process, turning it into a “headache”. As practice has shown, measuring volumes is much simpler, faster and easier than weighing the product on a scale.
That's why, not only in the kitchen measuring portions of boric acid in grams we try to "weave" without weights, but and with large quantities of product, technologists structure production operations in such a way as to “loop” weighing, bypassing it through the volume. This “loophole”, which allows us to measure the weight of a product without scales, is well known to us from physics. It’s not for nothing that smart people came up with bulk density and volumetric weight. These values, in fact, turn out to be a simple linear relationship between the volume and mass of the product. What this means in practice is that if we know the bulk density or volumetric weight of a product, then by measuring the volume we can easily calculate its mass. Let's measure the serving size with a tea, table or dessert spoon, why not? Not everyone can measure quantities in cubic meters, cubic meters, cubes and other nonsense such as buckets, barrels, cars or tanks.
In theory, everything is great, however, When using this method of measuring in practice, “sides” always arise. Volumetric weight turned out to be a value very sensitive to a large number a wide variety of factors. Even a slight change in the particle size of the product, storage duration, caking (read: density), not to mention a change in humidity (amount of water), immediately finds a serious reflection in the bulk density value. It turns out that the same volume can weigh more or less depending on the variety, quality or moisture content. If you think that this has little effect on how many grams of boric acid are in a teaspoon, then you are mistaken. It has a noticeable effect.
But even greater “discrepancies” in how many grams are introduced by our measuring instruments themselves. How much teaspoon of boron powder is NOT the same as how much scoop of product , although the volume is declared the same, equal to 5 ml. We just try to use them as measuring spoons and it turns out really bad. After all, the shape of a teaspoon (see photo) is very similar to a small spatula. It is almost impossible to fill it clearly without a slide (you have to try very hard). And the size of the slide or top is arbitrary for everyone, just look at the photo. The picture we get is that we are firmly convinced that we are measuring 5 ml with a teaspoon, but in fact we are taking some completely different volume of a portion of the product. Which? I would call this volume “unpredictable” - this is the most accurate definition. Add to this the fact that cutlery is only approximately rated by the manufacturer in terms of capacity. In fact, any spoons can only conditionally, with great stretch, be considered standard utensils. Their volume varies greatly. Or are you suggesting that the Chinese “sleep and see” how they could more accurately observe the volume of dishes in milliliters? Yeah, they’re trying especially for us, only to make it clearer to us how many grams of boric acid are in a teaspoon.
Why then does everyone want to know? how many grams of boric acid are in a teaspoon and measure out the portion specifically to her if “everything is so bad”? Yes because:
- Firstly: comfortable.
- Secondly: fast.
- Thirdly:"on the drum" accuracy, an error even twice does not change anything particularly, a couple of grams "here and there" does not play any role.
- Fourth: may not know that the method is extremely crude and inaccurate.
- Fifth: and this is the main reason - EVERYONE DOES THIS.
