How to convert Electron Volts to Joules
Multiply the electron volts value by 1.6022e-19: 1 eV = 1.6022e-19 J. Going the other way, 1 J = 6.2415e+18 eV, so divide by 1.6022e-19 or use the Joules to Electron Volts converter.
About these units
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.
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.
