About this calculator
The electron-volt is the natural energy unit in atomic and particle physics. 1 eV = the kinetic energy gained by one electron accelerating through 1 V. Common scales: chemical bonds ~1-5 eV, X-rays keV to MeV, particle physics MeV to GeV (LHC produces TeV-scale events).
Frequently asked
Atomic/molecular energies are tiny in joules (10⁻¹⁹). Using eV gives single-digit numbers that are easy to think about.
