Electronvolts to Kiloelectronvolts converter (eV to keV)
Convert Electronvolts (eV) to Kiloelectronvolts (keV) 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 Electronvolts to Kiloelectronvolts
1 electronvolt (eV) is equal to 0.001 kiloelectronvolts (keV).
E(keV) = E(eV) ÷ 1000
Divide electronvolts by 1000:
Example: Convert 1000 eV to keV:
E(keV) = 1000 ÷ 1000 = 1 keV
What is a Electronvolts?

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