How to Convert Gigaelectron Volt to Electron Volt

To convert from Gigaelectron Volt (GeV) to Electron Volt (eV), multiply the value by 1,000,000,000.0000002.

Formula: eV = GeV × 1.000000e+9

Reverse: GeV = eV × 1.000000e-9

Step-by-Step Example

Start with your value in Gigaelectron Volt. For example: 5 GeV
Multiply by the conversion factor: 5 x 1,000,000,000.0000002
The result is: 5,000,000,000 eV

About Gigaelectron Volt

The gigaelectron volt (GeV) is a unit of energy and work. One gigaelectron volt equals 1.602177 × 10^-10 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.

About Electron Volt
