Kelvin scale
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 Kelvin’s. The
International Practical Temperature Scale (1968, revised 1990) realizes the Kelvin scale over a wide range of temperatures Compare.
