Kelvin Temperature Scale

</dt>
An absolute temperature scale independent of the thermometric properties of the working substance. On this scale, the difference between two temperatures T1 and T2 is proportional to the heat converted into mechanical work by a Carnot engine operating between the isotherms and adiabats through T1 and T2. Also called absolute temperature scale, thermodynamic temperature scale. </dd>
For convenience the Kelvin is identified with the Celsius degree. The ice point in the Kelvin scale is 273.15 degrees K. The triple point of water, the fundamental reference points, is 273.16 degrees K. See absolute zero, approximate absolute temperature scale, Rankine temperature scale. </dd>
