What is the mass equivalent of 1 eV/c2?
It is common in particle physics, where units of mass and energy are often interchanged, to express mass in units of eV/ c2, where c is the speed of light in vacuum (from E = mc2 ). It is common to simply express mass in terms of “eV” as a unit of mass, effectively using a system of natural units with c set to 1. The mass equivalent of 1 eV/c2 is

How much is an electronvolt?
An electronvolt is the amount of kinetic energy gained or lost by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. Hence, it has a value of one volt, 1 J/C, multiplied by the electron’s elementary charge e, 1.602 176 634 × 10−19 C. Therefore, one electronvolt is equal to 1.602 176 634 × 10−19 J.
What is the electronvolt?
In high-energy physics, the electronvolt is often used as a unit of momentum. A potential difference of 1 volt causes an electron to gain an amount of energy (i.e., 1 eV ). This gives rise to usage of eV (and keV, MeV, GeV or TeV) as units of momentum, for the energy supplied results in acceleration of the particle.

For example, an electron and a positron, each with a mass of 0.511 MeV/c2, can annihilate to yield 1.022 MeV of energy. The proton has a mass of 0.938 GeV/c2. In general, the masses of all hadrons are of the order of 1 GeV/c2, which makes the GeV (gigaelectronvolt) a convenient unit of mass for particle physics:
