What is OKEI

OKEI is the abbreviation for the All-Russian Classification of Units of Measurement. The classifier is part of the Unified Coding and Classification System for Social and Technical and Economic Information in 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 designations 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 European Commission, the Commodity Nomenclature for 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 physical quantities".

Why was OKEI created?

The classifier is intended for use during problem solving quantification social and technical and economic indicators for the implementation of state reporting and accounting, forecasting and development of the economy, the implementation of foreign and domestic trade, providing statistical international comparisons, organizing customs control, 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 OKEI

In OKEI, units of measurement are divided into 7 groups: units of length, area, volume, mass, technical units and units of time, as well as economic units. For a number of units of measurement, submultiples and multiples have been introduced. The All-Russian classifier of units of measurement contains two reference appendices and two sections.

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

The identification code of the unit of measurement is a digital three-digit decimal code, which was assigned according to the serial-order coding system. In Annex A and the first section, codes are used that completely coincide with the codes of the international classification. Also in the second section, decimal 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 features 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 given in Appendix B. In the second column, the number of the application or section in which the unit of measurement is located is indicated. The third column is the identification code of the unit of measurement.

The maintenance of the All-Russian classifier of units of measurement is carried out by VNIIKI of the State Standard of the Russian Federation together with the Computing Center of the State Statistics Committee of the Russian Federation, the Center for Economic Conjuncture under the Government of Russia.

This lesson will not be new for beginners. We all heard from school such things as a centimeter, a meter, a kilometer. And when it came to mass, they usually said grams, kilograms, tons.

Centimeters, meters and kilometers; grams, kilograms and tons have one common name - units of measurement of physical quantities.

In this lesson, we will look at the most popular units of measurement, but we will not go deep into this topic, since units of measurement go into the field of physics. Today we are forced to study part of physics, as we need it for further study of mathematics.

Lesson content

Length units

The following units of measurement are used to measure length:

millimeters;
centimeters;
decimeters;
meters;
kilometers.

millimeter(mm). You can even see millimeters with your own eyes if you take the ruler that we used at school every day.

Small lines that follow each other in a row are millimeters. More precisely, the distance between these lines is one millimeter (1 mm):

centimeter(cm). On the ruler, each centimeter is indicated by a number. For example, our ruler, which was in the first figure, had a length of 15 centimeters. The last centimeter on this ruler is marked with the number 15.

There are 10 millimeters in one centimeter. You can put an equal sign between one centimeter and ten millimeters, since they denote the same length:

1cm=10mm

You can see for yourself if you count the number of millimeters in the previous figure. You will find that the number of millimeters (distance between lines) is 10.

The next unit of length is decimeter(dm). There are ten centimeters in one decimeter. Between one decimeter and ten centimeters, you can put an equal sign, since they denote the same length:

1 dm = 10 cm

You can verify this if you count the number of centimeters in the following figure:

You will find that the number of centimeters is 10.

The next unit of measure is meter(m). There are ten decimeters in one meter. Between one meter and ten decimeters, you can put an equal sign, since they denote the same length:

1 m = 10 dm

Unfortunately, the meter cannot be illustrated in the figure, because it is rather large. If you want to see the meter live, take a tape measure. Everyone has it in the house. On a tape measure, one meter will be designated as 100 cm. This is because there are ten decimeters in one meter, and one hundred centimeters in ten decimeters:

1 m = 10 dm = 100 cm

100 is obtained by converting one meter to centimeters. This is a separate topic, which we will consider a little later. In the meantime, let's move on to the next unit of length, which is called a kilometer.

The kilometer is considered the largest unit of measurement for length. Of course, there are other older units, such as a megameter, a gigameter, a terameter, but we will not consider them, since a kilometer is enough for us to further study mathematics.

There are a thousand meters in one kilometer. You can put an equal sign between one kilometer and a thousand meters, since they denote the same length:

1 km = 1000 m

Distances between cities and countries are measured in kilometers. For example, the distance from Moscow to St. Petersburg is about 714 kilometers.

International system of units SI

The international system of units SI is a certain set of generally accepted physical quantities.

The main purpose of the international system of SI units is to reach agreements between countries.

We know that the languages and traditions of the countries of the world are different. There's nothing to be done about it. But the laws of mathematics and physics work the same everywhere. If in one country “twice two is four”, then in another country “twice two is four”.

The main problem was that for each physical quantity there are several units of measurement. For example, we have just learned that there are millimeters, centimeters, decimeters, meters and kilometers for measuring length. If several scholars speaking different languages, will gather in one place to solve some problem, then such a large variety of units of measurement of length can give rise to contradictions between these scientists.

One scientist will claim that in their country length is measured in meters. The second might say that in their country, length is measured in kilometers. The third one can offer his own unit of measure.

Therefore, the international system of units SI was created. SI is an abbreviation for the French phrase Le Système International d'Unités, SI (which in Russian means - the international system of units SI).

The SI lists the most popular physical quantities and each of them has its own generally accepted unit of measurement. For example, in all countries, when solving problems, it was agreed that the length would be measured in meters. Therefore, when solving problems, if the length is given in another unit of measurement (for example, in kilometers), then it must be converted to meters. We will talk about how to convert one unit of measure to another a little later. In the meantime, let's draw our international system of units SI.

Our drawing will be a table of physical quantities. We will include each studied physical quantity in our table and indicate the unit of measurement that is accepted in all countries. Now we have studied the units of measurement of length and learned that meters are defined in the SI system for measuring length. So our table will look like this:

Mass units

Mass is a measure of the amount of matter in a body. In the people, body weight is called weight. Usually, when something is weighed, they say "it weighs so many kilograms" , although we are not talking about weight, but about the mass of this body.

However, mass and weight are different concepts. Weight is the force with which a body acts on a horizontal support. Weight is measured in newtons. And mass is a quantity that shows the amount of matter in this body.

But there is nothing wrong with calling the mass of the body weight. Even in medicine they say "human weight" , although we are talking about the mass of a person. The main thing is to be aware that these are different concepts.

The following units of measure are used to measure mass:

milligrams;
grams;
kilograms;
centners;
tons.

The smallest unit of measure is milligram(mg). Milligram most likely you will never put into practice. They are used by chemists and other scientists who work with small substances. It is enough for you to know that such a unit of mass measurement exists.

The next unit of measure is gram(G). In grams, it is customary to measure the amount of a product when compiling a recipe.

There are a thousand milligrams in one gram. You can put an equal sign between one gram and a thousand milligrams, since they denote the same mass:

1 g = 1000 mg

The next unit of measure is kilogram(kg). The kilogram is a common unit of measure. It measures everything. The kilogram is included in the SI system. Let's also include one more physical quantity in our SI table. We will call it "mass":

There are a thousand grams in one kilogram. Between one kilogram and a thousand grams, you can put an equal sign, since they denote the same mass:

1 kg = 1000 g

The next unit of measure is centner(c). In centners, it is convenient to measure the mass of a crop harvested from a small area or the mass of some kind of cargo.

There are one hundred kilograms in one centner. An equal sign can be put between one centner and one hundred kilograms, since they denote the same mass:

1 q = 100 kg

The next unit of measure is ton(t). In tons, large loads and masses of large bodies are usually measured. For example, mass spaceship or car.

There are a thousand kilograms in one ton. You can put an equal sign between one ton and a thousand kilograms, since they denote the same mass:

1 t = 1000 kg

Time units

We don't need to explain what time is. Everyone knows what time is and why it is needed. If we open the discussion to what time is and try to define it, then we will begin to delve into philosophy, and this is not what we need now. Let's start with time units.

The following units of measurement are used to measure time:

seconds;
minutes;
watch;
day.

The smallest unit of measure is second(With). Of course, there are also smaller units such as milliseconds, microseconds, nanoseconds, but we will not consider them, since at the moment there is no point in this.

In seconds, various indicators are measured. For example, how many seconds does it take an athlete to run 100 meters. The second is included in the international SI system of units for measuring time and is denoted as "s". Let's also include one more physical quantity in our SI table. We will call it "time":

minute(m). There are 60 seconds in one minute. You can put an equal sign between one minute and sixty seconds, since they represent the same time:

1 m = 60 s

The next unit of measure is hour(h). There are 60 minutes in one hour. You can put an equal sign between one hour and sixty minutes, since they represent the same time:

1 h = 60 m

For example, if we studied this lesson for one hour and we are asked how much time we spent studying it, we can answer in two ways: "we studied the lesson for one hour" or so "we studied the lesson for sixty minutes" . In both cases, we will answer correctly.

The next unit of time is day. There are 24 hours in a day. Between one day and twenty-four hours you can put an equal sign, since they denote the same time:

1 day = 24 hours

How is strength measured? In what units is force measured?

Back in school, we taught that the concept of strength Introduced into physics by a man who had an apple fall on his head. By the way, it fell due to gravityquot ;. Newton seems to have been his last name. So he called the unit of measurement of force. Although he could have called it an apple, it still hit him on the head!

According to the International System of Units (SI), force is measured in Newtons.

According to the Engineering System of Units, force is measured in ton-force, kilogram-force, gram-force, and so on.

According to the CGS System of Units, the unit of force is the dyne.

In the USSR, for some time, to measure force, they used such a unit of measurement as the wall.

In addition, in physics there are so-called natural units, according to which the force is measured in Planck forces.

- What is the strength in, brother?
- Newtons bro...
(Physics stopped being taught at school?)

Strength is one of the most widely known concepts in physics. Under force is understood as a quantity that is a measure of the impact on the body from other bodies and various physical processes.

With the help of force, not only the movement of objects in space can occur, but also their deformation.

The action of any force on a body obeys Newton's 3 laws.

Unit of measurement force in the international system of units SI is newton. It is marked with the letter H.

1N is a force, under the influence of which on a physical body with a mass of 1 kg, this body acquires an acceleration equal to 1 ms.

An instrument used to measure force is dynamometer.

It is also worth noting that a number of physical quantities are measured in other units.

For example:

Current strength is measured in Amps.

The intensity of light is measured in Candela.

In honor of the outstanding scientist and physicist Isaac Newton, who did a lot of research into the nature of the existence of processes that affect the speed of a body. Therefore, in physics it is customary to measure the force in newtons(1 N).

In physics, such a concept as force measured in newtons. They gave the name newtons, in honor of the famous and prominent physicist named Isaac Newton. In physics, there are 3 Newton's laws. The unit of force is also called the newton.

Force is measured in newtons. The unit of force is 1 Newton (1 N). The very name of the unit of measurement of force comes from the name of the famous scientist, whose name was Isaac Newton. He created 3 laws classical mechanics, which are called Newton's 1st, 2nd and 3rd laws. In the SI system, the unit of force is called the Newton (N). Latin the force is denoted by newton (N). Previously, when there was no SI system yet, the unit for measuring force was called the dyne, which was formed from the carrier of one instrument for measuring force, which was called a dynamometer.

Pascal (Pa, Pa)

Pascal (Pa, Pa) is a unit of pressure in the International System of Units of Measurement (SI system). The unit is named after the French physicist and mathematician Blaise Pascal.

Pascal is equal to the pressure caused by a force equal to one newton (N), evenly distributed over a surface normal to it with an area of \u200b\u200bone square meter:

1 pascal (Pa) ≡ 1 N/m²

Multiple units are formed using standard SI prefixes:

1 MPa (1 megapascal) = 1000 kPa (1000 kilopascals)

Atmosphere (physical, technical)

Atmosphere is a non-systemic unit of pressure, approximately equal to atmospheric pressure on the Earth's surface at the level of the World Ocean.

There are two approximately equal units with the following name:

Physical, normal or standard atmosphere (atm, atm) - exactly equal to 101,325 Pa or 760 millimeters of mercury.

Technical atmosphere (at, at, kgf/cm²)- equal to the pressure produced by a force of 1 kgf, directed perpendicularly and evenly distributed along flat surface with an area of 1 cm² (98,066.5 Pa).

1 technical atmosphere = 1 kgf / cm² (“kilogram-force per square centimeter”). // 1 kgf = 9.80665 newtons (exactly) ≈ 10 N; 1 N ≈ 0.10197162 kgf ≈ 0.1 kgf

On the English language kilogram-force is denoted as kgf (kilogram-force) or kp (kilopond) - kilopond, from the Latin pondus, meaning weight.

Notice the difference: not pound (in English "pound"), but pondus.

In practice, they approximately accept: 1 MPa = 10 atmospheres, 1 atmosphere = 0.1 MPa.

Bar

Bar (from the Greek βάρος - gravity) is a non-systemic unit of pressure, approximately equal to one atmosphere. One bar is equal to 105 N/m² (or 0.1 MPa).

1 m3/hour = 16.667 l/min = 0.2777 l/s = 0.5885 cfm

1 cfm (cubic foot per minute) = 0.47195 l/s = 28.31685 l/min = 1.699011 cfm/hour

Flow capacity / Valve flow characteristics

Flow coefficient (factor) Kv

Flow Factor - Kv

The main parameter of the shut-off and regulating body is the flow coefficient Kv. The flow coefficient Kv indicates the volume of water in cubic meters per hour (cbm/h) at a temperature of 5-30ºC, passing through the valve with a head loss of 1 bar.

Flow coefficient Cv

Flow Coefficient - Cv

In inch countries, the Cv factor is used. It shows how much water in gallon/minute (gpm) at 60ºF passes through a valve for a 1 psi pressure drop across the valve.

Kinematic viscosity / Viscosity

1 ft = 12 in = 0.3048 m

1 in = 0.0833 ft = 0.0254 m = 25.4 mm

1 m = 3.28083 ft = 39.3699 in

Force units
