electronvolt
The electronvolt is the energy gained by an electron crossing one volt of electric potential — about 1.602 × 10⁻¹⁹ joules.
Electronvolts describe particle physics energies, semiconductor band gaps, and atomic-scale phenomena.

About these units
Short background on the units used in this conversion.
Joule (J)
The joule is the SI unit of energy — the work done when one newton moves an object one meter.
Joules quantify electricity bills (as kWh), food energy (as kcal), and scientific energy transfers.
Frequently asked questions
How many joules are in one electronvolt?
One electronvolt equals joules. Multiply your electronvolts value by to convert to joules.
What is the conversion formula?
J = electronvolt × The reverse is
electronvolt = J × , using the same exact factors as this converter.Is this electronvolt to Joule converter private?
