How It Works
How to Convert Electron Volts to Joules
Formula
Joules = eV × 1.602176634 × 10⁻¹⁹
One electron volt is the energy gained by a single electron when accelerated through an electric potential difference of one volt. It is an extremely small unit of energy used in atomic and particle physics.
Worked Example
Convert 1 eV to joules.
- 01J = 1 × 1.602176634 × 10⁻¹⁹
- 02J = 1.602176634 × 10⁻¹⁹ J
