Volt to electron volt


How to use our volt to electron volt calculator?

The volt to electron volt calculator is easy to use. First, set the value of the voltage, then the electric charge and the calculator will directly give the energy in electron volt. The calculator can also give the result in joule. This can be achieved by changing the unit (eV).

With the calculator, it is also possible to get the voltage from the electric charge and the energy. But also the electric charge from the voltage and the energy.

What is the definition of electron volt?

In physics, the electron volt (also written electron-volt and electronvolt) is the measurement of the amount of kinetic energy gained by an electron accelerating from rest through an electric potential difference of one volt in vacuum.

Electron volt formula

The definition of the electron volt is expressed with the following formula:

eV = V x e


  • eV is the energy in electron volt (eV)
  • V is the voltage (V)
  • e is the elementary electric charge of an electron (e)


The electron volt is not an SI unit. Indeed, the SI unit of energy is the joule (J).


The common symbol for electron volt is eV.

Electron volt to joule

The joule (J) is the SI unit of energy. The electron volt can be converted to joule. Indeed, one electron volt corresponds to 1.602176634 x 10-19 J.
