To convert degrees Celsius to Kelvin (°C to K) and to convert Kelvin to Celsius degrees (K to °C), you may use the converter above. Alternatively, you may use the Celsius to Kelvin conversion table for a fast lookup.

Below, you will find information of how to convert degrees Celsius to Kelvin and how to convert Kelvin to Celsius degrees, including the formulas and example conversions.

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.

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 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
