About degrees Celsius and kelvins

Kelvin uses the same size degree as Celsius but starts at absolute zero, so the conversion is a straight addition of 273.15. Kelvin values are never negative, and they're written without a degree sign (300 K, not 300 °K).

Frequently asked questions

What is the formula to convert Celsius to Kelvin?
K = °C + 273.15. For example, 37 °C works out to 310.15 K.
How do I convert 37 degrees Celsius to kelvins?
Apply K = °C + 273.15 to 37 °C: the result is 310.15 K.
Can a temperature in Kelvin be negative?
No. 0 K is absolute zero (−273.15 °C), the lowest temperature physically possible, so the Kelvin scale has no negative values.
