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).
n. pl. kelvin Abbr. K
1. 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.
2. 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.
[After First Baron Kelvin.]

Kelvin, First Baron. Title of William Thomson 1824-1907.
British mathematician and physicist known especially for his work on heat and electricity. In 1848 he proposed a scale of temperature independent of any physical substance, which became known as the Kelvin scale.

(K) A scale of temperature measurement in which each degree is equal to 1⁄273.16 of the interval between 0 K (absolute zero) and the triple point of water. K = °C + 273.16. Named after William Thomson, Lord Kelvin (1824–1907).
