Electronvolt (eV)
The electronvolt is used in atomic, nuclear, and quantum physics for very small energies.
History: the electronvolt arose in particle physics as the energy of an electron crossing one volt of potential difference.
Quickly convert electronvolts to watt-hours without lookup tables or manual math.
This page is focused on converting electronvolts to watt-hours. Type a number into the first field and the result appears immediately in the second field.
Example: 1 eV = 0 Wh. Conversion formula: result = value × 1.602176634E-19 / 3600.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.

The watt-hour measures energy consumed or produced by one watt of power over one hour.
History: the watt-hour came from electrical engineering as the energy of one watt of power over one hour.
Enter a value in the Electronvolt field. The converter applies the formula "result = value × 1.602176634E-19 / 3600" and immediately shows the result in watt-hours.
