Joules to Electron Volts Conversion

Convert between Joules (J) and Electron Volts (eV) with precision

Joule (J)

The standard SI unit of energy. One joule equals the energy transferred when:

  • A force of 1 newton moves an object 1 meter
  • 1 watt of power is applied for 1 second

Electron Volt (eV)

The energy gained by an electron moving across a potential difference of 1 volt. Common in:

  • Particle physics
  • Atomic and nuclear physics
  • Semiconductor physics

Conversion Formula

eV = J ร— (6.242 ร— 1018) or eV = J / (1.602 ร— 10-19)

Where:

  • eV = Energy in electron volts
  • J = Energy in joules
