kelvin
[kel′vin]
adjective
designating or of a scale of thermodynamic temperature measured from absolute zero (-273.16°C): the formula for converting Celsius to Kelvin is °K=°C + 273.16
Origin of Kelvin
after 1st Baron Kelvinnoun
a basic unit of temperature on this scale, equal to one degree Celsius: abbrev. K
Kelvin,
1st Baron (William Thomson) 1824-1907; Brit. physicist & mathematician
kelvin
noun
pl. kelvin 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. See Table at 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.
Origin of kelvin
After First Baron Kelvin., First Baron. Title of William Thomson. 1824–1907.
British physicist who developed the Kelvin scale of temperature (1848) and supervised the laying of a trans-Atlantic cable (1866).

kelvin - Computer Definition
See K.
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). See color temperature and SI units.
