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).
SI Units: Temperature. The Kelvin (K) is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. The temperature 0 K is commonly referred to as absolute zero.. On the widely used Celsius temperature scale, water freezes at 0 Â°C and boils at about 100 Â°C.
