What is electron volt?

The electronvolt (or electron volt) is a unit of energy equal to 1.60217656535x10-19 joules (1 eV = 1.60217656535x10-19 J), the SI derived unit of energy. It is also equal to 1.60217656535x10-10 nanojoules (nJ), or 1.60217656535x10-16 millijoules (mJ), or 1.60217656535x10-22 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.

The SI is an abbreviation for the International System of Units.
