Kelvin scale (redirected from Kelvin scales)

Kelvin scale

n

(Physics / General Physics) a thermodynamic temperature scale based upon the efficiencies of ideal heat engines. The zero of the scale is absolute zero. Originally the degree was equal to that on the Celsius scale but it is now defined so that the triple point of water is exactly 273.16 kelvins. The International Practical Temperature Scale (1968, revised 1990) realizes the Kelvin scale over a wide range of temperatures Compare Rankine scale

Kelvin scale

A scale of temperature beginning at absolute zero (-273.15°C or -459.67°F). Each degree, or kelvin, represents the same temperature increment as one degree on the Celsius scale. On the Kelvin scale water freezes at 273.15 K and boils at 373.15 K.
