William Thomson, 1st Baron, 1824–1907, English physicist and mathematician.
(lowercase) the basic unit of temperature in the International System of Units (SI), formally defined to be approximately 1/273 of the triple point of water.
Abbreviation: K.
Thermodynamics. noting or pertaining to an absolute scale of temperature (Kelvin scale) in which the degree intervals are equal to those of the Celsius scale and in which absolute zero is 0 degrees Kelvin and the triple point of water has the value of approximately 273 degrees Kelvin.

The SI unit used to measure temperature, the basic unit of the Kelvin scale. A difference of one degree Kelvin corresponds to the same temperature difference as a difference of one degree Celsius. See Table at measurement. See also absolute zero.
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.
