Megaelectronvolts to Electronvolts converter (MeV to eV)
Convert Megaelectronvolts (MeV) 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 Megaelectronvolts to Electronvolts
1 megaelectronvolt (MeV) is equal to 1,000,000 electronvolts (eV).
E(eV) = E(MeV) × 1,000,000
Multiply MeV by 1,000,000:
Example: Convert 1 MeV to eV:
E(eV) = 1 × 1,000,000 = 1,000,000 eV

How this calculator works
The form on this page is a Megaelectronvolts-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.
