kelvin(kel -vin) Symbol: K. The SI unit of temperature, equal to 1/273.16 of the thermodynamic temperature of the triple point of water. A temperature in kelvin may be converted to one in degrees Celsius (°C) by the subtraction of 273.15.
the unit of thermodynamic temperature, equal to 1/273.16 of the thermodynamic temperature of the triple point of water; designation K. It was named after W. Thomson (Lord Kelvin). Before 1968 it was called the degree Kelvin (°K). The kelvin is used as the unit of the International Practical Temperature Scale and is one of the fundamental units of the International System of Units. The kelvin is equal in magnitude to a degree Celsius (°C).
