0 Kelvin to Celsius
0 K = -273.15 °C
0 kelvins equals -273.15 degrees Celsius.
How to convert 0 K to °C
Use the formula °C = K − 273.15:
°C = 0 − 273.15°C = -273.15
So 0 K = -273.15 °C.
Rounded values and quick estimate
- Rounded to a whole number: -273 °C
- Rounded to one decimal place: -273.2 °C
This conversion is exact, so there is no need to estimate: just add or subtract 273.15.

About kelvin and celsius
The kelvin is the SI unit of temperature. It starts at absolute zero (0 K = −273.15 °C) and uses degrees the same size as Celsius, so it never goes negative.
The Celsius scale sets the freezing point of water at 0 °C and its boiling point at 100 °C (at sea level). It is used for everyday temperatures in almost every country.
