Temperature Conversion between Kelvin and Celsius

The unit of temperature for all gas problems is Kelvin. Whereas the celsius scale is based on the boiling point and freezing point of water, 0 ºC and 100 ºC respectively, the Kelvin scale is based on the lowest possible temperature absolute zero, which is 0 K. There are no negative numbers in the Kelvin scale.

To convert between celsius and Kelvin temperatures, use the following equation:

kelvin-conversion

The boiling point of water is 100 ºC. In Kelvin, the boiling point of water is:

kelvin-bp-water

The freezing point of water is 0 ºC. In Kelvin, the freezing point of water is:

kelvin-fp-water

Absolute zero is 0 K. In celsius, absolute zero is:
