Electron Volt

Electron volt (eV)

It is a unit of energy. One eV is equal to the amount of energy one electron acquires by accelerating (from rest) through a potential difference of one volt. It is sometimes used as a measure of particle energies though it’s not an SI (System International) unit. The SI unit for energy is the joule. 1 eV = 1.602 x 10-19 joule.

Volts (V): It is the SI unit of Electric Potential, defined as the difference of potential between two points on a conductor carrying a constant current of one ampere when the power dissipated between the points is one watt.

Elementary charge unit: The elementary charge, usually denoted by e or sometimes qe, is the electric charge carried by a single proton or, equivalently, the magnitude of the electric charge carried by a single electron, which has charge −1 e. This elementary charge is a fundamental physical constant. e is sometimes called the elementary positive charge.

Conversion according to charge unit type:

eV to volts with elementary charge
The voltage V in volts (V) is up to the energy (E) in electron-volts (eV), divided by the electric charge Q in elementary charge or proton/electron charge (e):
V(V) = E(eV) / Q(e)
The elementary charge is the charge of one electron with the e symbol.
So,
volt = electron-volt / elementary charge
or
V = eV / e

eV to volts to with coulombs
The voltage V in volts(V) is equal to 1.602176565×10-19 times the energy E in electron-volts (eV), divided by the electrical charge Q in coulombs (C):
V(V) = 1.602176565×10-19 × E(eV) / Q(C)
So,
volt = 1.602176565×10-19 × electron-volt / coulomb
or
V = 1.602176565×10-19 × eV / C
