Celsius

Celsius or centigrade is a unit of temperature.

The freezing/melting point of water is about zero degrees celsius (0 °C) at a pressure of 1 atmosphere.

The boiling point of water is about one hundred degrees celsius (100 °C) at a pressure of 1 atmosphere.

The exact values depend on the water composition (usually the amount of salt) and the air pressure.

Seawater contains salt and the freezing point is reduced below 0 °C.

When boiling water on a mountain above sea level the boiling point is reduced below 100 °C.

The symbol of Celsius degrees is °C.

Kelvin

Kelvin is a unit of temperature.

The freezing/melting point of water is about 273.15K at a pressure of 1 atmosphere.

The symbol of Kelvin unit is K.

How to convert Celsius to Kelvin

0 degrees Celsius is equal to 273.15 Kelvin:

0 °C = 273.15 K

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15

Example

Convert 20 degrees Celsius to Kelvin:

T(K) = 20°C + 273.15 = 293.15 K
