# Electron-volts to volts calculator

How to convert energy in electron-volts (eV) to electrical voltage in volts (V).

You can calculate volts from electron-volts and elementary charge or coulombs, but you can't convert electron-volts to volts since electron-volt and volt units represent different quantities.

### eV to volts calculation with elementary charge

The voltage *V* in volts (V) is equal 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 electric charge of 1 electron with the e symbol.

So

volt = electronvolt / elementary charge

or

V = eV / e
