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

About celsius and kelvin
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.
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.
