Conversion Formulas

K = °C + 273.15

°C = K - 273.15

Quick Reference

-273.15 °C = 0 K
0 °C = 273.15 K
25 °C = 298.15 K
100 °C = 373.15 K
0 K = -273.15 °C
300 K = 26.85 °C

Convert between Celsius (°C) and Kelvin (K) instantly. Kelvin is the SI base unit for temperature used in scientific and engineering applications. Unlike Celsius and Fahrenheit, Kelvin starts at absolute zero (-273.15°C), the lowest theoretically possible temperature.
