From Wikipedia, the free encyclopedia.

The kelvin (symbol: K) is a unit to measure temperature. It is one of the seven SI base units. It is defined by two factors: zero kelvin is absolute zero (when molecular motion stops), and one kelvin is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water (0.01 °C). The Celsius temperature scale is now defined in terms of the kelvin.

It is named after the physicist and engineer William Thomson, who became Lord Kelvin when he was made a peer.

The kelvin as an SI unit is correctly written with a lowercase k (unless at the beginning of a sentence), and is never preceded by the words degree or degrees, or the symbol °, like Fahrenheit, or Celsius. This is because the latter are scales of measurement, whereas the kelvin is a unit of measurement. Note that the symbol for a kelvin is always a capital K.
