The volume is a three-dimensional space that fills the substance. On the other hand, this value (otherwise called - container) shows how many substances can fit in an empty vessel. For the convenience of solving problems, in physics, the volume is made to designate the letter V and measured in m³. The cubic meter (the name speaks for itself) is a cube, height, length whose width is 1 meter. However, there are a number of other units of volume. Talk about them in detail further.

Derived from the cube. Meters are: dm³, cm³, mm³, etc. We know the school that 1 cube. DM is 1 liter. The capacity with the size of the parties of the cube of 10 cm places liquid smoothly liter. Why measure in liters is often used to calculate medium body volumes? We learn from the example. We need to determine the volume of our body. Easily calculate V if the body has the right form. Measured the dimensions, multiplied, and ready. Unfortunately, the human figure is not a cube, not a cylinder. So, Archimedes found that the volume of water displaced from the bathroom filled to edge is proportional to the V body. The mass of liquid 60 kg is identical to 60 liters and 0.06 m³.
In different countries there are other dimensions of V. For bulk, liquid consistencies, generate measurements are used. Almost everyone heard that oil still believes in the barrels. Such a measure was born back in 1866. At that time, oil was poured into a barrel of 159 liters, which is equal to 42 gallons and 1 barrel. What favorably was such a provider? Convenient for sale, transportation. Separed raw materials with full decks, exactly 20 barrels were located on the barges, railway platforms. One man could ride himself, move it.

In chemistry to determine the amount of substances in gas, used molar volume. Vm \u003d V / N; where n is the amount, V - volume, Vm is a molar volume, which is 22.4 l / mol (provided that it is the perfect gas). The molar volume is measured in l / mol, dm³ / mol, cm³ / mol.

Prior to the introduction of a metric system to measure small fluid volumes, an oz was used. One oz corresponds to 29.573 ml of substance. Widely used this measure in the perfumery industry and pharmacies. However, the value of ounces in different countries was slightly different. So, in the US, it was equated with 30 ml, and in Britain - 28,413 ml.

In Scotland, Great Britain, USA, Ireland to determine the volume of alcoholic beverages are used by Djill. In our place - half a cup (somewhere 142 ml). However, the capacity of cups is different. Here in the establishments of these states now our customers are poured in different ways, the usual measure of a quarter of Jill: 24 ml or 35 ml. The owner is entitled to set the amount of alcohol.

To solve a challenge in physics, chemistry, it is convenient to use converter units. Suppose you need to know how many cubic meters are 870 DL (decylitrov). We introduce 870 in the field where decilters are written. Opposite the cube. Meters is displayed 0.087.
After reading the article carefully, it will be easier for you to find out the volume in the necessary units of measurement. Especially when a young mistress wishes to cook something delicious to dinner, it will not be much difficult to calculate how many milliliters add wine to fish. After all, thanks converter For culinary recipes, you can determine the container of the tablespoon and a glass. Then pour the required amount.
