What is OKEI

OKEI is the abbreviated name of the All-Russian Classifier of Units of Measurement. The classifier is part of the Unified System of Coding and Classification of Social and Technical and Economic Information of Russia. The All-Russian Classifier of Units of Measurement was introduced on the territory of Russia instead of the All-Union Classifier, known as the “System of designation of units and measurements used in automated control systems.” A classifier has been developed based on the international classification of units of measurement of the UN Economic Commission for Europe, the Commodity Nomenclature of Foreign Economic Activity and other significant documents. The all-Russian classifier of units of measurement is associated with GOST 8.417-81 "State system for ensuring the uniformity of measurements. Units of physical quantities."

Why was OKEI created?

The classifier is intended for use when solving problems of quantitative assessment of social and technical and economic indicators for state reporting and accounting, forecasting and economic development, foreign and domestic trade, ensuring statistical international comparisons, organizing customs control, and regulating foreign economic activity. In OKEI, classification objects are units of measurement that are used in these areas of activity.

What is the code structure in OKEY

In OKEI, units of measurement are divided into 7 groups: units of length, area, volume, mass, technical units and time units, as well as economic units. For a number of units of measurement, submultiple and multiple units have been introduced. The All-Russian Classifier of Units of Measurement contains two reference applications and two sections.

Each position in OKEI structurally consists of three blocks: identification, name and a block where additional characteristics are indicated.

The identification code of a unit of measurement is a digital three-digit decimal code, which was assigned according to the serial-ordinal coding system. Appendix A and the first section use codes that completely coincide with the international classification codes. Also in the second section, decimal digital three-digit codes were used, taken from the reserve of international classification codes.

In OKEI, the formula for the structure of the identification code is as follows: XXX. The name block is the name of the unit of measurement adopted in state reporting and accounting (for the second section), or the name of the unit of measurement according to the international classification (for Appendix A and the first section). The block of additional characteristics is conditional data, letter codes for units of measurement (national and international).

In order to facilitate the use of the classifier, an alphabetical index of units of measurement is provided in Appendix B. The second column indicates the number of the application or section in which the unit of measurement is located. The third column is the identification code of the unit of measurement.

The All-Russian Classifier of Measurement Units is maintained by the VNIIKI of the State Standard of the Russian Federation together with the Computer Center of the State Statistics Committee of the Russian Federation and the Center for Economic Conjuncture under the Government of Russia.

General information

Volume is the space occupied by a substance or object. Volume can also refer to the free space inside a container. Volume is a three-dimensional quantity, unlike, for example, length, which is two-dimensional. Therefore, the volume of flat or two-dimensional objects is zero.

Volume units

Cubic meter

The SI unit of volume is the cubic meter. The standard definition of one cubic meter is the volume of a cube with edges one meter long. Derived units such as cubic centimeters are also widely used.

Liter

The liter is one of the most commonly used units in the metric system. It is equal to the volume of a cube with edges 10 cm long:
1 liter = 10 cm × 10 cm × 10 cm = 1000 cubic centimeters

This is the same as 0.001 cubic meters. The mass of one liter of water at a temperature of 4°C is approximately equal to one kilogram. Milliliters, equal to one cubic centimeter or 1/1000 of a liter, are also often used. Milliliter is usually denoted as ml.

Jill

Gills are units of volume used in the United States to measure alcoholic beverages. One jill is five fluid ounces in the British Imperial system or four in the American system. One American jill is equal to a quarter of a pint or half a cup. Irish pubs serve strong drinks in portions of a quarter jill, or 35.5 milliliters. In Scotland, portions are smaller - one fifth of a jill, or 28.4 milliliters. In England, until recently, portions were even smaller, just one-sixth of a jill or 23.7 milliliters. Now, it’s 25 or 35 milliliters, depending on the rules of the establishment. The owners can decide for themselves which of the two portions to serve.

Dram

Dram, or drachma, is a measure of volume, mass, and also a coin. In the past, this measure was used in pharmacy and was equal to one teaspoon. Later, the standard volume of a teaspoon changed, and one spoon became equal to 1 and 1/3 drachms.

Volumes in cooking

Liquids in cooking recipes are usually measured by volume. Bulk and dry products in the metric system, on the contrary, are measured by mass.

Tea spoon

The volume of a teaspoon is different in different measurement systems. Initially, one teaspoon was a quarter of a tablespoon, then - one third. It is the latter volume that is now used in the American measurement system. This is approximately 4.93 milliliters. In American dietetics, the size of a teaspoon is 5 milliliters. In the UK it is common to use 5.9 milliliters, but some diet guides and cookbooks use 5 milliliters. The size of a teaspoon used in cooking is usually standardized in each country, but different sizes of spoons are used for food.

Tablespoon

The volume of a tablespoon also varies depending on the geographic region. So, for example, in America, one tablespoon is three teaspoons, half an ounce, approximately 14.7 milliliters, or 1/16 of an American cup. Tablespoons in the UK, Canada, Japan, South Africa and New Zealand also contain three teaspoons. So, a metric tablespoon is 15 milliliters. A British tablespoon is 17.7 milliliters, if a teaspoon is 5.9, and 15 if a teaspoon is 5 milliliters. Australian tablespoon - ⅔ ounce, 4 teaspoons, or 20 milliliters.

Cup

As a measure of volume, cups are not defined as strictly as spoons. The volume of the cup can vary from 200 to 250 milliliters. A metric cup is 250 milliliters, and an American cup is slightly smaller, approximately 236.6 milliliters. In American dietetics, the volume of a cup is 240 milliliters. In Japan, cups are even smaller - only 200 milliliters.

Quarts and gallons

Gallons and quarts also have different sizes depending on the geographic region where they are used. In the Imperial system of measurement, one gallon is equal to 4.55 liters, and in the American system of measurements - 3.79 liters. Fuel is generally measured in gallons. A quart is equal to a quarter of a gallon and, accordingly, 1.1 liters in the American system, and approximately 1.14 liters in the Imperial system.

Pint

Pints ​​are used to measure beer even in countries where the pint is not used to measure other liquids. In the UK, milk and cider are measured in pints. A pint is equal to one-eighth of a gallon. Some other countries in the Commonwealth of Nations and Europe also use pints, but since they depend on the definition of a gallon, and a gallon has a different volume depending on the country, pints are also not the same everywhere. An imperial pint is approximately 568.2 milliliters, and an American pint is 473.2 milliliters.

Fluid ounce

An imperial ounce is approximately equal to 0.96 US ounces. Thus, an imperial ounce contains approximately 28.4 milliliters, and an American ounce contains approximately 29.6 milliliters. One US ounce is also approximately equal to six teaspoons, two tablespoons, and one eighth cup.

Volume calculation

Liquid displacement method

The volume of an object can be calculated using the fluid displacement method. To do this, it is lowered into a liquid of a known volume, a new volume is geometrically calculated or measured, and the difference between these two quantities is the volume of the object being measured. For example, if when you lower an object into a cup with one liter of water, the volume of the liquid increases to two liters, then the volume of the object is one liter. In this way, you can only calculate the volume of objects that do not absorb liquid.

Formulas for calculating volume

The volume of geometric shapes can be calculated using the following formulas:

Prism: the product of the area of ​​the base of the prism and the height.

Rectangular parallelepiped: product of length, width and height.

Cube: length of an edge to the third power.

Ellipsoid: product of semi-axes and 4/3π.

Pyramid: one third of the product of the area of ​​the base of the pyramid and the height. Post a question in TCTerms and within a few minutes you will receive an answer.

Conditional fuel called fuel, the calorific value of 1 kg or 1 nm³ of which is equal to 7000 kcal. It is most often measured in tons, so a common abbreviation in various sources is here.(means it is a ton of equivalent fuel).
