Convert kelvins to degrees Celsius

Convert kelvins (K) to degrees Celsius (°C) with the formula °C = K − 273.15.

0 K = -273.15 °C

Kelvin to Celsius formula

°C = K − 273.15

Use the formula °C = K − 273.15.

Example: To convert 0 K to degrees Celsius: 0 − 273.15 = -273.15 °C.

Frequently asked questions

How do I convert kelvins to degrees Celsius?

Use the formula °C = K − 273.15. To convert 0 K to degrees Celsius: 0 − 273.15 = -273.15 °C.

Is the Kelvin to Celsius conversion exact?

Yes. The formula follows directly from how the temperature scales are defined, so it is exact; results are rounded for display.

Can a temperature in kelvin be negative?

No. The Kelvin scale starts at absolute zero, 0 K (−273.15 °C or −459.67 °F), the lowest possible temperature, so kelvin values are never negative.

What is 0 K in degrees Celsius?

0 K = -273.15 °C.

How do I convert degrees Celsius back to kelvins?

Use the formula K = °C + 273.15. The Celsius to Kelvin page has a converter and a full table.
