One joule equals approximately 6.242 × 10^18 electronvolts. The electronvolt is an extremely small energy unit used in atomic and particle physics.
Multiply the joule value by 6.242 × 10^18. For example, 1.602 × 10^-19 J × 6.242 × 10^18 = 1 eV.
An electronvolt is the energy gained by a single electron moving across a potential difference of one volt. It equals 1.602 × 10^-19 joules.
Electronvolts are standard in particle physics, nuclear physics, X-ray spectroscopy, and semiconductor physics. Particle accelerators measure beam energies in MeV, GeV, or TeV.
