Convert electron volts to

electron volt (unit of energy), pl. electron volts, abbr. eV

The electron volt conversion selector selects the energy measurement unit to convert to starting from electron volts (eV). To make a conversion starting from a unit of energy other than electron volt, simply click on the "Reset" button.

About electron volt

The electron volt, or electronvolt, is a unit of energy equal to 1.60217656535 × 10-19 joules (1 eV = 1.60217656535 × 10-19 J), the SI derived unit of energy.

The electron volt (eV) is also equal to 1.60217656535 × 10-10 nanojoules (nJ), or 1.60217656535 × 10-16 millijoules (mJ), or 1.60217656535 × 10-22 kilojoules (kJ) or 0.001 kiloelectronvolts (keV).

The electronvolt is the kinetic energy gained by a free electron when it travels through a potential difference of one volt.

Although the electronvolt is not an SI unit, it is typically used with SI prefixes. Common multiples and subdivisions of electronvolt include millielectronvolts (or milli-electron volts), kiloelectronvolts (or kilo-electron volts), megaelectronvolts (or mega-electron volts), gigaelectronvolts (or giga-electron volts), teraelectronvolts (or tera-electron volts), etc.

  • 1 millielectronvolt (meV) = 0.001 electronvolts (eV)
  • 1 kiloelectronvolt (keV) = 1,000 electronvolts (eV)
  • 1 megaelectronvolt (MeV) = 1,000,000 electronvolts (eV)
  • 1 gigaelectronvolt (GeV) = 1,000,000,000 electronvolts (eV)
  • 1 teraelectronvolt (TeV) = 1,000,000,000,000 electronvolts (eV)

The electronvolt is commonly used in physics for measuring the energies of elementary particles.
