Kelvin

kelvin, abbr. K, official name in the International System of Units (SI) for the degree of temperature as measured on the Kelvin temperature scale.

Kelvin

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, 0ºC (freezing water) is equal to 273.15K, and 100ºC (boiling water) is equal to 373.15K. From British physicist and mathematician Lord William Thomas Kelvin (1824-1907). See color temperature and SI units.

kelvin [′kel·vən]

(electricity)

A name formerly given to the kilowatt-hour. Also known as thermal volt.

(thermodynamics)

A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. Symbolized K. Formerly known as degree Kelvin.

kelvin (K)

The International Standard unit of temperature. Absolute zero equals 0°K = -273.16°C = 459.69°F. A temperature increase of 1°K is numerically equal to an increase of 1°C.

Kelvin 

the unit of thermodynamic temperature, equal to 1/273.16 of the thermodynamic temperature of the triple point of water; designation K. It was named after W. Thomson (Lord Kelvin). Before 1968 it was called the degree Kelvin (°K). The kelvin is used as the unit of the International Practical Temperature Scale and is one of the fundamental units of the International System of Units. The kelvin is equal in magnitude to a degree Celsius (°C).
