How to convert Celsius to Kelvin?

To convert Celsius to Kelvin, add 273.15 to the Celsius value.

For example, to convert 30 Celsius to Kelvin, add 273.15 to 30, that makes 30 Celsius is equal to 303.15 Kelvin.

Celsius to Kelvin conversion formula:

Kelvin = Celsius + 273.15

How to convert Kelvin to Celsius?

To convert Kelvin to Celsius, subtract 273.15 from the Kelvin value.

For example, to convert 300 Kelvin to Celsius degrees, subtract 273.15 from 300, that makes 26.85 degrees Celsius is equal to 300 Kelvin.

Kelvin to Celsius conversion formula:

Celsius = Kelvin - 273.15

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

What is Celsius?

Celsius or Centigrade is a unit of temperature in the metric system where the freezing point of water is 0 degree and the boiling point of water is 100 degrees under standard atmospheric pressure (101.325 kPa). It is named after the Swedish astronomer Anders Celsius (1701–1744). The symbol is "°C".

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