How to convert Celsius to Kelvin?

To convert degrees Celsius to Kelvin, add 273.15 to Celsius degrees.

For example, to convert 30 °C to Kelvin, add 273.15 to 30, that makes 303.15 Kelvin.

Kelvin = Celsius + 273.15

For all temperature units converter including Celsius to Kelvin conversion, please check temperature conversion.

How to convert Kelvin to Celsius?

To convert Kelvin to Celsius, subtract 273.15 from Kelvin.

Celsius = Kelvin - 273.15

What is Celsius?

Celsius (Centigrade) is a temperature scale with the freezing point of water is 0 degree and the boiling point of water is 100 degrees under standard atmospheric pressure (101.325 kPa). The symbol is "°C"

Freezing point of water = 0 °C
Boiling point of water = 100 °C
Absolute zero = -273.15 °C

What is Kelvin?

Kelvin is the base unit of temperature in metric system and formally defined as 1/273.16 of the thermodynamic temperature of the triple point of pure water. The symbol is "K".

Freezing point of water = 273.15 K
Boiling point of water = 373.15 K
Absolute zero = 0 K
