Very often in culinary recipes indicatedthat you want to take a certain amount of an ingredient, specified in tablespoons or teaspoons. Therefore, to convert a product to milliliters or milligrams, you need to know the volume of a tablespoon.
Считается, что в современной России или в странах former CIS spoon for the first holds 18 ml of liquid. In other countries, the volume of a tablespoon is different: in the USA, as well as in Canada and New Zealand, this volume is expressed as 15 ml. In Australia, a tablespoon holds a little more - 20 ml.
This confusion is a little confusing, isn't it?And if you look in the drawer with cutlery, then almost every hostess will find that in her arsenal there are spoons of completely different samples. So the confidence that each of them has a volume of 18 ml melts without a trace.
Of course, if the hostess is taken to pickle cabbage orpickled vegetables, a very big problem does not arise when reading the recipe. But it is not recommended to use this device for measuring off drugs without first calculating its volume.
How can you calculate the volume of a tablespoon?Very simple! However, for the "laboratory work" you need any container with divisions (today such glasses-beakers are often on sale) or a faceted glass with a risk, with a capacity of 200 ml.
With a tablespoon we have to fill a glass with water.by marks. It is necessary to try to fill the device as much as possible, as they say, “with a slide”; water from it should not be spilled past the glass. Each filling should be noted, for example, put aside a coin or throw a pea into the cup. Of course, you can write on paper - as you wish. But it is better not to rely on your own memory, as it is easy to lose count.
После того как воды набралось достаточно (по risk in a glass), you should do arithmetic calculations. For example, I had 13 tablespoons of water in my glass. So, you need 200 ml: 13 = 15.4 ml. From here I conclude that the volume of a tablespoon I have is equal to 15.4 ml, and not at all 18, as many ancient reference books claim.
The second "laboratory work" will be aimed atit is to find out how many milliliters of bulk products a tablespoon can hold. Again we carry out similarly to the first, only water is replaced by flour or sugar, decoy or salt.
You can spend two calculations: for the spoon, which we fill "without a hill" and for such, filled with the top.
In the same way you can calculate the capacitydessert or volume of a teaspoon. The accuracy of these calculations is, of course, approximate. It depends on the number of "overflows" in the glass. That is, the more of these actions, the more approximate the result. And, accordingly, the less you have to pour water with a spoon, the more accurately you can calculate the indicator of interest.
Hence, the calculation of the volume of a tablespoon is more accuratethan tea. However, most manipulations with the latter indicate that almost all modern Russian teaspoons contain 5 ml of liquid.
The same is claimed by all sorts of reference books. To the question, how many in a teaspoon ml, they give the answer that in Russia and the countries of the former CIS this device has a volume of 5 milliliters.
Slightly different volumes of teaspoons in the United States and England. It is indicated that in the United States of America it is equal to 4.93 ml, and the English one holds only 3.55 ml.
As for drugs, more oftenjust today at the pharmacy, the consumer receives a medicine or syrup, to which a device for use is applied, mainly a plastic spoon of the required volume. So in this case, problems should not arise.
The difficulty is only making anduse of drugs made by the recipe of traditional medicine. For accuracy, pharmacy measures can be saved, which are sold along with the preparations.
