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 × (6.242 × 1018)
or
eV = J / (1.602 × 10-19)
Where:
- eV = Energy in electron volts
- J = Energy in joules
Common Conversions
