Kelvin absolute temperature scale

[′kel·vən ¦ab·sə‚lūt ′tem·prə·chər ‚skāl]
(thermodynamics)
A temperature scale in which the ratio of the temperatures of two reservoirs is equal to the ratio of the amount of heat absorbed from one of them by a heat engine operating in a Carnot cycle to the amount of heat rejected by this engine to the other reservoir; the temperature of the triple point of water is defined as 273.16 K. Also known as Kelvin temperature scale.
