释义
kelvin(symbol: K)

Electronics and Electrical Engineering
  • The basic SI unit of thermodynamic temperature, defined as 1/273.16 of the thermodynamic temperature of the triple point of water, i.e. the equilibrium point at which pure ice, air-free water, and water vapour can coexist in a sealed vacuum flask. It is related to the degree Celsius (°C):

    t°C=T273.15kelvin

    where T is the thermodynamic temperature and 273.15  K is the temperature of the ice point, which is the zero of the Celsius (or centigrade) temperature scale.

    The kelvin is also used as a unit of temperature difference, in which case it is identical to the degree Celsius.
