How do you convert Kelvin to Celsius?

To convert a temperature from Kelvin to Celsius, you subtract 273.15 from the Kelvin temperature. This adjustment is necessary because the Kelvin scale starts at absolute zero, which is equivalent to -273.15 degrees Celsius. Therefore, to find the Celsius equivalent of a temperature measured in Kelvin, the subtraction of 273.15 effectively shifts the starting point of the temperature scale to align with the Celsius scale.

For example, if you have a temperature of 300 K and you wish to convert it to Celsius, you would calculate:

Celsius = 300 K - 273.15 = 26.85 °C.

This relationship between Kelvin and Celsius is fundamental in thermodynamics and is widely used in scientific contexts.
