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.

ev = 1
  1. 01J = 1 × 1.602176634 × 10⁻¹⁹
  2. 02J = 1.602176634 × 10⁻¹⁹ J
