One electronvolt equals approximately 1.602 × 10^-19 joules. This is an extremely small amount of energy, appropriate for atomic-scale processes.
Multiply the eV value by 1.602 × 10^-19. For example, 13.6 eV × 1.602 × 10^-19 = 2.179 × 10^-18 J (the hydrogen ionization energy).
Visible light photons carry 1.8-3.1 eV. Chemical bond energies range from 1-10 eV. X-rays are in the keV range. Nuclear reactions involve MeV energies.
One eV is the kinetic energy gained by an electron accelerated through a 1-volt potential. The charge of an electron (1.602 × 10^-19 coulombs) times 1 volt gives the energy in joules.
