How to Convert Hartree to Gigaelectron Volt

To convert from Hartree (Eh) to Gigaelectron Volt (GeV), multiply the value by 2.721139e-8.

Formula: GeV = Eh × 2.721139e-8

Reverse: Eh = GeV × 36,749,322.17565495

Step-by-Step Example

Start with your value in Hartree. For example: 5 Eh
Multiply by the conversion factor: 5 x 2.721139e-8
The result is: 1.360569e-7 GeV

About Hartree

The hartree (Eh) is a unit of energy and work. One hartree equals 4.359745 × 10^-18 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 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.
