The '''kelvin''' (symbol K, named after [[Lord Kelvin]]) is the unit of [[temperature]], and specifically of [[absolute temperature scale|absolute temperature]]. It is 1/273.16 of the absolute temperature of the [[triple point]] of [[water]]. The size of the kelvin is the same as the size of the [[Celsius]] degree, and thus to convert from degrees Celsius to kelvins, one adds 273.15. (The zero of the Celsius scale, which is the [[melting point]] of water ice under standard atmospheric pressure, happens to be 273.15 kelvins.) Note that one says '200 kelvins' not '200 ''degrees'' kelvin'.
