About these units
The Celsius scale sets water freezing at 0 and boiling at 100 degrees at standard pressure. Process, mold, and oven temperatures worldwide are set in Celsius.
The kelvin is the SI absolute temperature unit, starting at absolute zero. Thermodynamic and gas-law calculations require temperatures in kelvin.
Common questions
What is 100 C in K?
100 C equals 373.15 K, using K = C + 273.15.
How do you convert Celsius to Kelvin?
Use K = C + 273.15. Temperature scales start from different zero points, so no single multiplier converts them; the formula includes an offset.
