How to Convert Kiloelectron Volt to Erg

To convert from Kiloelectron Volt (keV) to Erg (erg), multiply the value by 1.602177e-9.

Formula: erg = keV × 1.602177e-9

Reverse: keV = erg × 624,150,907.4460763

Step-by-Step Example

Start with your value in Kiloelectron Volt. For example: 5 keV
Multiply by the conversion factor: 5 x 1.602177e-9
The result is: 8.010883e-9 erg

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 Erg

The erg (erg) is a unit of energy and work. One erg equals 1.000000 × 10^-7 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.
