Kelvin

Kelvin

The fundamental unit of temperature. It is not calibrated in terms of the freezing and boiling points of water, but in terms of energy itself. The number 0 K is assigned to the lowest possible temperature, called absolute zero. The sizes of the "degree" are the same as on the Celsius scale. On the Kelvin scale, the freezing point of water is 273 K and the boiling point is 373 K.
