Kelvin (symbol K) - unit of measure for temperature in the SI system, one of the seven basic units of the system.

Kelvin, according to an international agreement is determined by two points: absolute zero and the triple point of water. Absolute zero temperature, by definition, is precisely 0 K and -273,15 °C. At absolute zero all kinetic motion of particles of matter stops (in the classical sense), and thus, the matter has no heat. The triple point of water, also by definition, is assigned to the temperature of 273,16 K and 0,01 °C. The consequence of these definitions of the two reference points of the absolute thermodynamic scale are:

- one Kelvin equals exactly 1/273.16 of the temperature of the triple point of water particles;

- one Kelvin equals exactly one degree Celsius;

- the difference between the two temperature scales is exactly 273.15 kelvin.

The unit is named after the British engineer and physicist William Lord Kelvin, who wrote of the need for an "absolute thermometric scale". In turn, this title came from the Kelvin River, which flows through the territory of the University of Glasgow.

To convert values ​​from Kelvin to degrees Celsius using the formula: [°C] = [K] − 273.15

To convert values ​​from Kelvin to degrees Fahrenheit using the formula: [°F] = [K] × 9⁄5 − 459.67
