How to convert kelvins to degrees Celsius

Temperature scales do not share the same zero point, so you cannot simply multiply. Use this formula:

°C = K − 273.15

Examples

0 K = -273.15 °C
273.15 K = 0 °C
373.15 K = 100 °C

About the units

Kelvin (K)

The kelvin is the SI base unit of temperature. 0 K is absolute zero, and a change of 1 K equals a change of 1 °C. It is used in science and engineering.

Degree Celsius (°C)

The Celsius scale sets 0 °C at the freezing point of water and 100 °C at its boiling point (at standard pressure). It is used for weather and cooking in almost every country.
