Unit definitions
- Joule (J)
- The joule is the SI unit of energy, equal to the work done by a force of one newton over one meter, or one watt for one second.
- Electronvolt (eV)
- An electronvolt is the energy gained by an electron moving through a potential difference of one volt, exactly 1.602176634 × 10⁻¹⁹ joules. It is used in atomic, nuclear and particle physics.
