How to Convert Kiloelectron Volt to Megaelectron Volt

To convert from Kiloelectron Volt (keV) to Megaelectron Volt (MeV), multiply the value by 0.001.

Formula: MeV = keV × 0.001

Reverse: keV = MeV × 1,000

Step-by-Step Example

Start with your value in Kiloelectron Volt. For example: 5 keV
Multiply by the conversion factor: 5 x 0.001
The result is: 0.005 MeV

About Kiloelectron Volt

The kiloelectron volt (keV) is a unit of energy and work. One kiloelectron volt equals 1.602177 × 10^-16 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 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.
