The Kelvin scale and the kelvin are named after the British physicist and engineer William Thomson, 1st Baron Kelvin , who wrote of the need for an âabsolute thermometric scaleâ. The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale where absolute zero, the theoretical absence of all thermal energy, is zero (0 K).
The Kelvin scale is based at absolute zero. The Kelvin scale was defined when the scientist William Thomson (1st Baron Kelvin) calculated the absolute minimum thermal energy an object can have. He decided to shift the Celsius scale so that 0 would be equivalent to having zero thermal energy (aka absolute zero).
