# Volts to eV calculator

## Volts to eV calculation with elementary charge

Enter the voltage in volts (V), electric charge in elementary charge (e), then press the Calculate button to get the result in electron-volts (eV).

Voltage in volts (V)
Electric charge in e

E(eV) = V(V) × Q(e)

The energy E in electron-volts (eV) is equal to the voltage V in volts (V), multiplied by the electric charge Q in elementary charge (e).

The elementary charge (symbol e) 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 −e.

## Volts to eV calculation with coulombs

Enter the voltage in volts (V), electric charge in coulombs (C), then press the Calculate button to get the result in electron-volts (eV).

Voltage in volts (V)
Electric charge in coulombs (C)

E(eV) = V(V) × Q(C) / 1.602176565×10-19

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