Kelvin in Science
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.
