How to convert Joules to Electron Volts
Multiply the joules value by 6.2415e+18: 1 J = 6.2415e+18 eV. Going the other way, 1 eV = 1.6022e-19 J, so divide by 6.2415e+18 or use the Electron Volts to Joules converter.
About these units
Joules (J)
The joule is the SI unit of energy: the work done by a force of one newton over one meter. Lifting a small apple one meter takes about one joule.
Electron Volts (eV)
An electronvolt is the energy an electron gains when accelerated through one volt, exactly 1.602176634 × 10⁻¹⁹ joules. Particle and photon energies are quoted in eV.
