Kelvin - Wikipedia
https://en.wikipedia.org/wiki/Kelvin
WEBThe kelvin, symbol K, is a unit of measurement for temperature. The Kelvin scale is an absolute scale, which is defined such that 0 K is absolute zero and a change of thermodynamic temperature T by 1 kelvin corresponds to a change of thermal energy kT by 1.380 649 × 10 −23 J.

Kelvin - Simple English Wikipedia, the free encyclopedia
https://simple.wikipedia.org/wiki/Kelvin
WEBDefinition. Lord Kelvin. The Kelvin scale is defined by a specific relationship between the pressure of a gas and the temperature. This says that "the pressure of the gas is directly proportional to the temperature in Kelvin". This means that Kelvin is an absolute temperature scale, and scientists use this scale more than any other.
