NCIt definition : A basic unit of thermodynamic temperature, one of the seven base units of the International
System of Units (Systeme International d'Unites, SI). It is 1/273.16th of the thermodynamic
temperature of the triple point of water. This sets the size of the kelvin unit for
temperature differences and defines the thermodynamic temperature of an equilibrium
mixture of waters ice-liquid-vapor as 273.16 K, where 0 K is the lowest possible temperature
(absolute zero).;
NCIt note : Named after the Scottish mathematician and physicist William Thomson 1st Lord Kelvin.;
