#### GeV to eV

In physics, an electronvolt (symbol eV, also written electron-volt and electron volt) is the amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equivalent to the numerical value of the charge of an electron in coulombs (symbol C). Under the 2019 redefinition of the SI base units, this sets 1 eV equal to the exact value 1.602176634×10−19 J.

Giga-electron volts to electron volts conversion calculator calculates how many electron volts are in 'X' giga-electron volts (where 'X' is the number of giga-electron volts to convert to electron volts). In order to convert a value from giga-electron volts to electron volts (from GeV to eV) simply type the number of GeV to be converted to eV and then click on the 'convert' button.

#### How to convert GeV to eV

One gigaelectron-volt is equal to 109 electron-volts:

1 GeV = 109 eV

The energy in electron-volts E(eV) is equal to the energy in gigaelectron-volts E(GeV) times 1000000000:

E(eV) = E(GeV) × 109 = E(GeV) × 1000000000

#### Example

Convert 5GeV to eV:

E(eV) = 5GeV × 109 = 5×109 eV
