-173.1°C
That's between absolute zero and the coldest place on Earth. Water freezes here: expect ice.
Convert the other way: °C to K
What it means
How warm is that?
Reference temperatures are typical values at sea level. Water boils lower up a mountain, where the air pressure is less.
The math
How to convert K to °C
Subtract 273.15: °C = K − 273.15. Absolute zero, 0 K, is −273.15 °C.
Example: 100 K = -173.15 °C.

About these units
Kelvin (K)
The kelvin is the SI unit of temperature and starts at absolute zero, −273.15 °C. Kelvin steps match Celsius steps, and the degree sign is not used.
Degrees Celsius (°C)
Celsius puts 0 at the melting point of ice and 100 at the boiling point of water at sea level. Almost every country uses it for weather and cooking.
