How Do You Convert Celsius to Kelvin?

The value of 0 degrees Celsius can be converted to 273.15 Kelvin:

0 °C is equivalent to 273.15 K.

To convert a temperature T from degrees Celsius (°C) to Kelvin (K), simply add 273.15 to the Celsius value:

T(K) = T(°C) + 273.15.

Example

Let’s say the temperature is 25 degrees Celsius and you want to convert it to Kelvin. To do this, simply add 273.15 to the Celsius value. In this case, the calculation would be 25 + 273.15 = 298.15 Kelvin.
