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.
