Gigaelectronvolts to Electronvolts converter (GeV to eV)
Convert Gigaelectronvolts (GeV) to Electronvolts (eV) with this free calculator. Type a value, press Convert, and the page applies the same factor shown in the formula below — no rounded shortcut, and nothing is stored on a server.
How to convert Gigaelectronvolts to Electronvolts
1 gigaelectronvolt (GeV) is equal to 10⁹ electronvolts (eV).
E(eV) = E(GeV) × 10⁹
Multiply GeV by 10⁹:
Example: Convert 1 GeV to eV:
E(eV) = 1 × 10⁹ = 1,000,000,000 eV
What is a Gigaelectronvolts?

How this calculator works
The form on this page is a Gigaelectronvolts-to-Electronvolts converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the eV result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
