Zero Celsius is not Zero Absolute temperature as in the Kelvin scale.

Explanation:

By extrapolation absolute zero would be about -273 degrees Celsius. As volume and pressure vary directly with absolute temperature it is necessary to change Celsius temperatures to absolute temperature values by changing to Kelvin for the equations to work.
