-100 Celsius to Kelvin
-100 °C = 173.15 K
-100 degrees Celsius equals 173.15 kelvins.
How to convert -100 °C to K
Use the formula K = °C + 273.15:
K = -100 + 273.15K = 173.15
So -100 °C = 173.15 K.
Rounded values and quick estimate
- Rounded to a whole number: 173 K

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.
