Formula: Eh = keV × 36.7493221757

Reverse: keV = Eh × 0.0272113862

Step-by-Step Example

Start with your value in Kiloelectron Volt. For example: 5 keV
Multiply by the conversion factor: 5 x 36.7493221757
The result is: 183.746611 Eh

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 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.
