Kelvin Temperature Scale

An absolute temperature scale in which a change of 1 Kelvin equals a change of 1 degree Celsius; 0°K is the lowest temperature on the Kelvin scale. The freezing point of water is +273°K (Kelvin) and the boiling point of +373°K. It is used primarily for scientific purposes. It is also known as the Absolute Temperature Scale.
