How to Convert Hartree to Kiloelectron Volt

To convert from Hartree (Eh) to Kiloelectron Volt (keV), multiply the value by 0.0272113862.

Formula: keV = Eh × 0.0272113862

Reverse: Eh = keV × 36.7493221757

Step-by-Step Example

Start with your value in Hartree. For example: 5 Eh
Multiply by the conversion factor: 5 x 0.0272113862
The result is: 0.136057 keV

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 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.
