# Units of measurement

Units of measurement are used to determine length and area, among other things. They are used in everyday life, for example when cooking, as well as when driving a car. We often use them even unconsciously when we check the weather or tell someone the distance between one place and another. 6 inches to cm. There are two systems for determining length – the SI system and imperial units. Find out what the differences between them are and how they can be converted.

Units of measurement are all units that help to define certain values, such as time, area, mass or length. Currently, the world distinguishes between two systems on the basis of which they are calculated and stated. It is useful to know not only the generally accepted European units, but also to have an idea of the basic units used, for example, in the United States. Such knowledge can be useful not only when travelling, but also when searching for recipes on the Internet.

A commonly accepted instrument or system, the standard unit of measurement (also called an etalon), is used to define and determine a certain value. The best example of an etalon is the metre, which was measured by a segment of the Paris meridian until 1960. Find out what the basic units of measurement are and how they can be converted quickly.

## SI units of measurement

The SI, or International System of Units, was introduced and approved in 1960. It consists of 7 basic units, which help to define length, mass, time, electric current, abundance of matter, luminosity and temperature. In everyday life, most people use 4 basic units, while the rest are derived from them. Below you will find all the units of measurement you may need in your everyday life.
