However, it's important to note that the zero points of the two scales are different:

* Celsius has its zero point at the freezing point of water.

* Kelvin has its zero point at absolute zero, which is the theoretical temperature at which all molecular motion stops.

Therefore, to convert between Celsius and Kelvin, you need to add or subtract 273.15:

* Kelvin to Celsius: °C = °K - 273.15

* Celsius to Kelvin: °K = °C + 273.15
