How to Convert Megaelectron Volt to Kiloelectron Volt

To convert from Megaelectron Volt (MeV) to Kiloelectron Volt (keV), multiply the value by 1,000.

Formula: keV = MeV × 1,000

Reverse: MeV = keV × 0.001

Step-by-Step Example

Start with your value in Megaelectron Volt. For example: 5 MeV
Multiply by the conversion factor: 5 x 1,000
The result is: 5,000 keV

About Megaelectron Volt

The megaelectron volt (MeV) is a unit of energy and work. One megaelectron volt equals 1.602177 × 10^-13 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 Kiloelectron Volt
