# Kelvin to degrees Celsius

**1 kelvin in degrees Celsius: 1 K = -272.15 °C**

°C = K − 273.15

To convert kelvin to degrees Celsius, use °C = K − 273.15. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is °C = K − 273.15. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor.

## Common questions

### How many degrees Celsius are in one kelvin?

One kelvin equals -272.15 degrees Celsius. °C = K − 273.15.

### How do you convert kelvin to degrees Celsius?

Use °C = K − 273.15. So 10 K is -263.15 °C.

### How many kelvin are in one degree Celsius?

One degree Celsius equals 274.15 kelvin, which is the reverse of the conversion above.
