About converting Kelvin to Celsius
This page converts Kelvin (K) to Celsius (°C). Enter a value above to get an immediate result with the target unit clearly shown.
Kelvin and Celsius conversion
Temperature scales use different zero points and intervals, so the calculator applies the appropriate temperature formula rather than a single multiplication factor.
Conversion example: 25 K equals -248.15 °C. Enter any temperature above to calculate a precise value for this pair of scales.
This Kelvin to Celsius conversion compares two units used to express thermal conditions on different temperature scales. Use Kelvin (K) as the source unit when your original value is recorded in that unit; the calculated result is then presented in Celsius (°C).
