About watt hours and electronvolts
Watt Hour (Wh)
A watt-hour (Wh) is the energy of one watt used for one hour, equal to 3,600 joules. Battery capacities are often given in Wh.
Electronvolt (eV)
An electronvolt (eV) is about 1.602 × 10⁻¹⁹ joules, the energy an electron gains across one volt. It is used in atomic and particle physics.
