## Volts to eV calculation with elementary charge

The energy *E* in electron-volts (eV) is equal to the voltage *V* in volts (V), times the
electric charge *Q* in elementary charge or proton/electron charge (e):

*E*_{(eV)} = *V*_{(V)}* *×* Q*_{(e)}

The elementary charge is the electric charge of 1 electron with the e symbol.

## Volts to eV calculation with coulombs

The energy E in electron-volts (eV) is equal to the voltage V in volts (V), times the electrical charge Q in coulombs (C) divided by 1.602176565×10^{-19}:

*E*_{(eV)} = *V*_{(V)}* *×* Q*_{(C)} / 1.602176565×10^{-19}
