Joule (J)
The joule is the SI unit of energy and connects mechanical work, heat, and electrical energy.
History: the joule is named after James Prescott Joule and is the SI unit of energy.
Quickly convert joules to electronvolts without lookup tables or manual math.
This page is focused on converting joules to electronvolts. Type a number into the first field and the result appears immediately in the second field.
Example: 1 J = 6.2415090745E+18 eV. Conversion formula: result = value × 1 / 1.602176634E-19.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.

History: the joule is named after James Prescott Joule and is the SI unit of energy.
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.
Enter a value in the Joule field. The converter applies the formula "result = value × 1 / 1.602176634E-19" and immediately shows the result in electronvolts.
1 J = 6.2415090745E+18 eV.
