How to convert from Kelvin to Celsius

Temperature is called the average kinetic energy of particles in the system, which is in thermodynamic equilibrium. This implies that temperature should be measured in energy units included in the SI system in Joules. But, historically, that the temperature was being measured long before the advent of molecular-kinetic theory and in practice using standard units – degrees. In international SI unit of measurement of the thermodynamic temperature of the body is the Kelvin (K), which is one of the seven base units in the system. In practice, however, most temperature is measured in degrees Celsius.

Instruction

On a scale of Kelvin temperature readout is conducted from the absolute zero – a condition in which are completely absent in thermal oscillations, one degree of the scale equal to 1/273,15 of the distance from absolute zero to the triple point of water. Triple point of water is the state at which ice, water and water vapor are in equilibrium. The notion of absolute temperature, introduced by W. Thomson (Kelvin), so this scale is named after him.

In the composition of the derivative values of SI for measuring temperature used Celsius. Celsius scale was proposed in 1742 by the Swedish scientist A. Celsius and is often used in practice. This scale is tied to basic characteristics of water, the temperature of melting ice (0 °C) and boiling point (100 °C). This scale is convenient because most natural processes occur in this temperature range. In fact, the boiling point and freezing point of water is defined is not precise enough, so the Celsius scale determined by the scale of Kelvin. Absolute zero thus defined as 0 K, which is equal to 273,15 °C .

For the transfer of body temperature from Kelvin to Celsius, Kelvin need to take 273,15, the resulting number will be equal to the body temperature expressed in degrees Celsius.
That is, 1 K = C + 273,15; 1 C = K – 273,15.
