kelvin

(kel -vin) Symbol: K. The SI unit of temperature, equal to 1/273.16 of the thermodynamic temperature of the triple point of water. A temperature in kelvin may be converted to one in degrees Celsius (°C) by the subtraction of 273.15.

Kelvin

Standard unit for color temperature, abbreviated K. A Kelvin unit is the basis of all temperature measurement, starting with 0 K at absolute zero.

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).

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

A thermometer scale starting at absolute zero (approximately −273°C) and having degrees of the same magnitude as those of the Celsius thermometer. Thus, 0°C = 273 K. Named after first Lord Kelvin (1824–1907). Also called an absolute scale.

kelvin

the basic SI unit of thermodynamic temperature; the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.

Kelvin

William Thomson, 1st Baron Kelvin. 1824--1907, British physicist, noted for his work in thermodynamics, inventing the Kelvin scale, and in electricity, pioneering undersea telegraphy

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.
