-273.15 Celsius to Kelvin
-273.15 °C = 0 K
-273.15 degrees Celsius equals 0 kelvins.
How to convert -273.15 °C to K
Use the formula K = °C + 273.15:
K = -273.15 + 273.15K = 0
So -273.15 °C = 0 K.
Rounded values and quick estimate
- Rounded to a whole number: 0 K
- Rounded to one decimal place: 0 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.
