How it works
How to convert kelvin to degrees Celsius
°C = K − 273.15.
About kelvin and degrees Celsius
The kelvin starts at absolute zero; 0 K is −273.15 °C, and one kelvin step equals one Celsius degree. On the Celsius scale water freezes at 0 °C and boils at 100 °C at sea level.
When you'd convert kelvin to degrees Celsius
Read lab data or colour temperature in everyday terms. Subtract 273.15.
Common mistake: temperature scales have different zero points, so you cannot just multiply; a change of 1 °C is a change of 1.8 °F, but 1 °C is not 1.8 °F.
To go the other way, use the degrees Celsius to kelvin converter.
