In physics, the **electronvolt** (symbol eV, also written electron-volt) is a unit of energy equal to approximately or 1.6×10^{−19} J.

By definition, it is the amount of energy gained (or lost) by the charge of a single electron moving across an electric potential difference of one volt.

The **electronvolt** is not a SI unit, and its definition is empirical (unlike the litre, the light-year and other such non-SI units), thus its value in SI units must be obtained experimentally.
