How to Convert Gigaelectron Volt to Kiloelectron Volt

To convert from Gigaelectron Volt (GeV) to Kiloelectron Volt (keV), multiply the value by 1,000,000.0000000002.

Formula: keV = GeV × 1,000,000.0000000001

Reverse: GeV = keV × 0.000001

Step-by-Step Example

Start with your value in Gigaelectron Volt. For example: 5 GeV
Multiply by the conversion factor: 5 x 1,000,000.0000000002
The result is: 5,000,000 keV

About Gigaelectron Volt

The gigaelectron volt (GeV) is a unit of energy and work. One gigaelectron volt equals 1.602177 × 10^-10 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

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.
