How to Calculate Kelvin to Celsius

What is Kelvin to Celsius?

Kelvin is the absolute temperature scale used in science. Celsius is derived from Kelvin by subtracting 273.15 — they use the same degree size, just different zero points. 0 K (absolute zero) = −273.15°C.

Formula

K = °C + 273.15

K: °C + 273 — °C + 273
C: K − 273 — K − 273

Step-by-Step Guide

1°C = K − 273.15
2K = °C + 273.15
3The degree size is identical between Kelvin and Celsius
4Used in gas law calculations, thermodynamics, and astronomy
