Kiloelectronvolts to Electronvolts converter (keV to eV)
Convert Kiloelectronvolts (keV) 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 Kiloelectronvolts to Electronvolts
1 kiloelectronvolt (keV) is equal to 1000 electronvolts (eV).
E(eV) = E(keV) × 1000
Multiply keV by 1000:
Example: Convert 5 keV to eV:
E(eV) = 5 × 1000 = 5000 eV

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