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 formula

Kelvin = Celsius + 273.15

How to convert Kelvin to Celsius?

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

Kelvin to Celsius 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
