The kelvin is the base unit of temperature in the International System of Units, It is named after the Belfast-born, Glasgow University engineer and physicist William Thomson.There are 100 degrees between the temperate at which water freezes at (273.16 K) and boils (373.16 K). Each unit on this scale, called a Kelvin rather than a degree, is equal to a degree on the Celsius scale. For this reason, just the K, not the degree symbol, is used when reporting temperatures in Kelvin.
