Joules to eV Converter
A joules to electron volts converter switches between the SI unit of energy (joule) and the electron volt (eV) used in atomic, nuclear, and particle physics.
- 11 eV = 1.602176634 × 10⁻¹⁹ J (exact by definition)
- 2eV = Joules / 1.602×10⁻¹⁹
- 3Joules = eV × 1.602×10⁻¹⁹
- 4keV = 10³ eV; MeV = 10⁶ eV; GeV = 10⁹ eV
1 joule=1 / 1.602×10⁻¹⁹ = 6.242×10¹⁸ eV
| Energy | eV | Context |
|---|---|---|
| Visible photon | 1.8–3.1 eV | Light |
| X-ray photon | 100 eV–1 keV | Medical X-ray |
| Alpha particle | 5 MeV | Radioactive decay |
| LHC proton | 6.5 TeV | Particle physics |
