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 kilojoules without lookup tables or manual math.
This page is focused on converting electronvolts to kilojoules. Type a number into the first field and the result appears immediately in the second field.
Example: 1 eV = 0 kJ. Conversion formula: result = value × 1.602176634E-19 / 1000.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.
