Celsius to Kelvin converter (°C to K)

How to convert Celsius to Kelvin

0 degrees Celsius is equal to 273.15 Kelvin. Absolute zero is −273.15°C = 0 K.

T(K) = T(°C) + 273.15

Add 273.15 to the Celsius temperature to get Kelvin:

T(K) = T(°C) + 273.15

Convert 20°C to Kelvin:

T(K) = 20°C + 273.15 = 293.15 K
