Origin of Kelvinafter Kelvin
nounpl. kelvin Abbr. K
- A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. One kelvin degree is equal to one Celsius degree. measurement
- Kelvin A temperature scale in which zero occurs at absolute zero and each degree equals one kelvin. Water freezes at 273.15 K and boils at 373.15 K.

- In the International System of Units, the base unit of thermodynamic temperature; 1/273.16 of the thermodynamic temperature of the triple point of water. Shown as "K".
- A unit interval on the Kelvin scale.
- The interval between the freezing and boiling points of water is 100 kelvins.
- (usually as postpositioned adjective) A unit for a specific temperature on the Kelvin scale.
- Ice melts above 273.15 kelvin.
- Water boils above 373.15 kelvin.
Named after the Irish-born Scottish physicist William Thomson, Lord Kelvin.
- Alternative capitalization of kelvin.
kelvin - Computer Definition
A unit of measurement of temperature. Part of the SI system of measurement, the Kelvin (K) scale starts at absolute zero (-273.15). Each Kelvin degree is the same as a Celsius degree. As a result, 0ÂºC (freezing water) is equal to 273.15K, and 100ÂºC (boiling water) is equal to 373.15K. From British physicist and mathematician Lord William Thomas Kelvin (1824-1907).
