Degrees Celsius to kelvin
1 degree Celsius in kelvin
1 °C = 274.15 K
K = °C + 273.15
To convert degrees Celsius to kelvin, use K = °C + 273.15. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works
The relationship is K = °C + 273.15. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor.
