The Kelvin (°K) is the base unit of the thermodynamic temperature in the International System (SI) of Units that is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
Reference Definition by NIST: The kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 x 10-23 when expressed in the unit J K-1, which is equal to kg m2 s-2 K-1, where the kilogram, meter and second are defined in terms of h, c and ΔνCs.
