This guide has been compiled from various sources. But its creation was prompted by a small book from the Mass Radio Library, published in 1964, as a translation of O. Kroneger’s book in the GDR in 1961. Despite its antiquity, it is my reference book (along with several other reference books). I think time has no power over such books, because the fundamentals of physics, electrical and radio engineering (electronics) are unshakable and eternal.

Relationships between units of magnetic quantities
in SGSM and SI systems
| In electrical engineering and reference literature published before the introduction of the SI system, the magnitude of the magnetic field strength N often expressed in oersteds (uh), magnitude of magnetic induction IN - in Gaussians (gs), magnetic flux Ф and flux linkage ψ - in Maxwells (μs). |
| 1e=1/4 π × 10 3 a/m; 1a/m=4π × 10 -3 e; 1gs=10 -4 t; 1tl=10 4 gs; 1μs=10 -8 vb; 1vb=10 8 μs |
| It should be noted that the equalities are written for the case of rationalized practical system ICSA, which was included in the SI system as an integral part. From a theoretical point of view, it would be more correct to O In all six relationships, replace the equal sign (=) with the correspondence sign (^). For example |
|
1e=1/4π × 10 3 a/m |
| which means: a field strength of 1 Oe corresponds to a strength of 1/4π × 10 3 a/m = 79.6 a/m |
| The fact is that units uh, gs And mks belong to the SGSM system. In this system, the unit of current is not fundamental, as in the SI system, but a derivative. Therefore, the dimensions of quantities characterizing the same concept in the SGSM and SI systems turn out to be different, which can lead to misunderstandings and paradoxes if we forget about this circumstance. When performing engineering calculations, when there is no basis for misunderstandings of this kind |
Non-system units
Some math and physical concepts
used in radio engineering
| Just like the concept of speed of movement, in mechanics and radio engineering there are similar concepts, such as the rate of change of current and voltage. They can be either averaged over the course of the process or instantaneous. |
|
i= (I 1 -I 0)/(t 2 -t 1)=ΔI/Δt |
| When Δt -> 0, we obtain instantaneous values of the rate of change of current. It most accurately characterizes the nature of the change in value and can be written as: |
|
i=lim ΔI/Δt =dI/dt |
| Moreover, you should pay attention - average values and instantaneous values can differ tens of times. This is especially clearly seen when a changing current flows through circuits with a sufficiently large inductance. |
decibel |
| To evaluate the ratio of two quantities of the same dimension in radio engineering, a special unit is used - the decibel. |
| K u = U 2 / U 1 Voltage gain; K u[db] = 20 log U 2 / U 1 Voltage gain in decibels. Ki[db] = 20 log I 2 / I 1 Current gain in decibels. Kp[db] = 10 log P 2 / P 1 Power gain in decibels. |
| The logarithmic scale also allows you to depict functions with a dynamic range of parameter changes of several orders of magnitude on a graph of normal sizes. |
| To determine the signal strength in the reception area, another logarithmic unit of the DBM is used - dicibels per meter. |
| P [dbm] = 10 log U 2 / R +30 = 10 log P + 30. [dbm]; |
| The effective voltage across the load at a known P[dBm] can be determined by the formula: |

Magnitude is something that can be measured. Concepts such as length, area, volume, mass, time, speed, etc. are called quantities. The value is measurement result, it is determined by a number expressed in certain units. The units in which a quantity is measured are called units of measurement.
To indicate a quantity, a number is written, and next to it is the name of the unit in which it was measured. For example, 5 cm, 10 kg, 12 km, 5 min. Each quantity has countless values, for example the length can be equal to: 1 cm, 2 cm, 3 cm, etc.
The same quantity can be expressed in different units, for example kilogram, gram and ton are units of weight. The same quantity in different units is expressed by different numbers. For example, 5 cm = 50 mm (length), 1 hour = 60 minutes (time), 2 kg = 2000 g (weight).
To measure a quantity means to find out how many times it contains another quantity of the same kind, taken as a unit of measurement.
For example, we want to find out the exact length of a room. This means we need to measure this length using another length that is well known to us, for example using a meter. To do this, set aside a meter along the length of the room as many times as possible. If it fits exactly 7 times along the length of the room, then its length is 7 meters.
As a result of measuring the quantity, we obtain or named number, for example 12 meters, or several named numbers, for example 5 meters 7 centimeters, the totality of which is called compound named number.
Measures
In each state, the government has established certain units of measurement for various quantities. An accurately calculated unit of measurement, adopted as a standard, is called standard or exemplary unit. Model units of the meter, kilogram, centimeter, etc. were made, according to which units for everyday use were made. Units that have come into use and are approved by the state are called measures.
The measures are called homogeneous, if they serve to measure quantities of the same kind. So, gram and kilogram are homogeneous measures, since they are used to measure weight.
Units
Below are units of measurement of various quantities that are often found in mathematics problems:
Weight/mass measures
- 1 ton = 10 quintals
- 1 quintal = 100 kilograms
- 1 kilogram = 1000 grams
- 1 gram = 1000 milligrams
- 1 kilometer = 1000 meters
- 1 meter = 10 decimeters
- 1 decimeter = 10 centimeters
- 1 centimeter = 10 millimeters
- 1 sq. kilometer = 100 hectares
- 1 hectare = 10,000 sq. meters
- 1 sq. meter = 10000 sq. centimeters
- 1 sq. centimeter = 100 square meters millimeters
- 1 cu. meter = 1000 cubic meters decimeters
- 1 cu. decimeter = 1000 cubic meters centimeters
- 1 cu. centimeter = 1000 cubic meters millimeters
Let's consider another quantity like liter. A liter is used to measure the capacity of vessels. A liter is a volume that is equal to one cubic decimeter (1 liter = 1 cubic decimeter).
Measures of time
- 1 century (century) = 100 years
- 1 year = 12 months
- 1 month = 30 days
- 1 week = 7 days
- 1 day = 24 hours
- 1 hour = 60 minutes
- 1 minute = 60 seconds
- 1 second = 1000 milliseconds
In addition, time units such as quarter and decade are used.
- quarter - 3 months
- decade - 10 days
A month is taken to be 30 days unless it is necessary to specify the date and name of the month. January, March, May, July, August, October and December - 31 days. February in a simple year - 28 days, February in leap year- 29 days. April, June, September, November - 30 days.
A year is (approximately) the time it takes for the Earth to complete one revolution around the Sun. It is customary to count every three consecutive years as 365 days, and the fourth year following them as 366 days. A year containing 366 days is called leap year, and years containing 365 days - simple. One extra day is added to the fourth year for the following reason. The Earth's revolution around the Sun does not contain exactly 365 days, but 365 days and 6 hours (approximately). Thus, a simple year is shorter than a true year by 6 hours, and 4 simple years are shorter than 4 true years by 24 hours, i.e., by one day. Therefore, one day is added to every fourth year (February 29).
You will learn about other types of quantities as you further study various sciences.

Measuring instruments
Special measuring instruments are used to measure various quantities. Some of them are very simple and designed for simple measurements. Such instruments include a measuring ruler, tape measure, measuring cylinder, etc. Other measuring instruments are more complex. Such devices include stopwatches, thermometers, electronic scales, etc.
Measuring instruments usually have a measuring scale (or scale for short). This means that there are line divisions on the device, and next to each line division the corresponding value of the quantity is written. The distance between the two strokes, next to which the value of the value is written, can be additionally divided into several smaller divisions; these divisions are most often not indicated by numbers.
It is not difficult to determine what value each smallest division corresponds to. So, for example, the figure below shows a measuring ruler:
The numbers 1, 2, 3, 4, etc. indicate the distances between the strokes, which are divided into 10 identical divisions. Therefore, each division (the distance between the nearest strokes) corresponds to 1 mm. This quantity is called at the cost of a scale division measuring device.
Before you begin measuring a value, you should determine the scale division value of the instrument you are using.
In order to determine the division price, you must:
- Find the two closest lines on the scale, next to which the values of the quantity are written.
- Subtract from greater value divide the smaller number and the resulting number by the number of divisions between them.
As an example, let’s determine the price of the scale division of the thermometer shown in the figure on the left.
Let's take two lines, near which the numerical values of the measured value (temperature) are plotted.
For example, bars indicating 20 °C and 30 °C. The distance between these strokes is divided into 10 divisions. Thus, the price of each division will be equal to:
(30 °C - 20 °C) : 10 = 1 °C
Therefore, the thermometer shows 47 °C.
Measure various quantities in Everyday life each of us has to do constantly. For example, in order to arrive at school or work on time, you have to measure the time that will be spent on the road. Meteorologists measure temperature, barometric pressure, wind speed, etc. to predict the weather.
Physical size called physical property material object, process, physical phenomenon, characterized quantitatively.
Physical quantity value expressed by one or more numbers characterizing this physical quantity, indicating the unit of measurement.
The size of a physical quantity are the values of numbers appearing in the value of a physical quantity.
Units of measurement of physical quantities.
Unit of measurement of physical quantity is a quantity of fixed size that is assigned a numerical value equal to one. It is used for the quantitative expression of physical quantities homogeneous with it. A system of units of physical quantities is a set of basic and derived units based on a certain system of quantities.
Only a few systems of units have become widespread. In most cases, many countries use the metric system.
Basic units.
Measure a physical quantity - means to compare it with another similar physical quantity taken as a unit.
The length of an object is compared with a unit of length, the mass of a body with a unit of weight, etc. But if one researcher measures the length in fathoms and another in feet, it will be difficult for them to compare the two values. Therefore, all physical quantities throughout the world are usually measured in the same units. In 1963, the International System of Units SI (System international - SI) was adopted.
For each physical quantity in the system of units there must be a corresponding unit of measurement. Standard units is its physical implementation.
The length standard is meter- the distance between two strokes applied on a specially shaped rod made of an alloy of platinum and iridium.
Standard time serves as the duration of any regularly repeating process, for which the movement of the Earth around the Sun is chosen: the Earth makes one revolution per year. But the unit of time is taken not to be a year, but give me a sec.
For a unit speed take the speed of such uniform rectilinear motion at which the body moves 1 m in 1 s.
A separate unit of measurement is used for area, volume, length, etc. Each unit is determined when choosing a particular standard. But the system of units is much more convenient if only a few units are selected as the main ones, and the rest are determined through the main ones. For example, if the unit of length is meter, then the unit of area would be square meter, volume - cubic meter, speed - meter per second, etc.
Basic units The physical quantities in the International System of Units (SI) are: meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), candela (cd) and mole (mol).

ANDmeasurements. To obtain an accurate, objective and easily reproducible description of a physical quantity, measurements are used. Without measurements, a physical quantity cannot be characterized quantitatively. Definitions such as “low” or “high” pressure, “low” or “high” temperature reflect only subjective opinions and do not contain comparisons with reference values. When measuring a physical quantity, a certain numerical value is assigned to it.
Measurements are carried out using measuring instruments. There is quite a large number of measuring instruments and devices, from the simplest to the most complex. For example, length is measured with a ruler or tape measure, temperature with a thermometer, width with calipers.
Measuring instruments are classified: by the method of presenting information (displaying or recording), by the method of measurement (direct action and comparison), by the form of presentation of readings (analog and digital), etc.
The following parameters are typical for measuring instruments:
Measuring range- the range of values of the measured quantity for which the device is designed during its normal operation (with a given measurement accuracy).
Sensitivity threshold- the minimum (threshold) value of the measured value, distinguished by the device.
Sensitivity- connects the value of the measured parameter and the corresponding change in the instrument readings.
Accuracy- the ability of the device to indicate the true value of the measured indicator.
Stability- the ability of the device to maintain a given measurement accuracy for a certain time after calibration.
