kelvin

n. Lord Kelvin, title of William Thompson (1824-1907), British physicist and mathematician who developed the Kelvin scale of temperature; unit of absolute temperature equal to 1/273.16 of the Kelvin scale temperature of the triple point of water

The kelvin (symbol: K) is a  unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale where absolute zero — the coldest possible temperature — is zero kelvins (0 K).The Kelvin scale and the kelvin are named after the Irish-born physicist and engineer William Thomson, 1st Baron Kelvin (1824 – 1907), who wrote of the need for an “absolute thermometric scale.”
