Temperature conversion uses a formula: C = K − 273.15. 1 K equals -272.15 C, and 1 C equals 274.15 K.
About these units
The kelvin is the SI absolute temperature unit, starting at absolute zero. Thermodynamic and gas-law calculations require temperatures in kelvin.
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.
Common questions
What is 373 K in C?
373 K equals 99.85 C, using C = K − 273.15.
How do you convert Kelvin to Celsius?
Use C = K − 273.15. Temperature scales start from different zero points, so no single multiplier converts them; the formula includes an offset.
