100 K to °C – 100 Kelvin in Celsius

How to convert 100 K to °C

Use the formula °C = K − 273.15:

°C = 100 − 273.15
°C = -173.15

So 100 K = -173.15 °C.

Rounded values and quick estimate

Rounded to a whole number: -173 °C
Rounded to one decimal place: -173.2 °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.
