How it’s calculated
°C = K − 273.15
- Temperature scales have different zero points, so the conversion adds or subtracts an offset as well as scaling.
- 1 K = -272.15 °C · 1 °C = 274.15 K

About these units
Kelvin (K)
SI (metric)
The SI base unit of temperature. 0 K is absolute zero, the coldest anything can get.

Degree Celsius (°C)
SI (metric)
Celsius uses the same step size as kelvin, shifted so water freezes at 0 °C: °C = K − 273.15.
