Celsius to Kelvin conversion (°C to K)

How to convert Celsius to Kelvin

0 degrees Celsius is equal to 273.15 degrees Kelvin:

0 °C = 273.15 K

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15

Example

Convert 20 degrees Celsius to Kelvin:

T(K) = 20°C + 273.15 = 293.15 K
