It is a non- SI unit of energy, accepted for use with SI.
In particle physics, masses are expressed in natural units, so factors of c are set equal to one and omitted. For example, an electron and a positron, each with a mass of 511 keV, can annihilate to yield 1.022 MeV of energy. The proton, a typical baryon, has a mass of 0.938 GeV, making GeV (often pronounced jev) a very convenient unit of mass for particle physics.

To convert a particle's energy in electronvolts into its temperature in kelvinThe kelvin (symbol: K is the SI unit of temperature, and is one of the seven SI base units. It is defined by two facts: zero kelvin is absolute zero (when molecular motion stops), and one kelvin is the fraction 1/273. 16 of the thermodynamic temperature o, multiply by 11,605 (see Boltzmann constantThe Boltzmann constant k or k is the physical constant relating temperature to energy. It is named after the Austrian physicist Ludwig Boltzmann, who made important contributions to the theory of statistical mechanics, in which this constant plays a cruci).
