What is a kiloelectron-volt (keV)?

A kiloelectron-volt is an energy unit equal to 1,000 electronvolts, commonly used in atomic, nuclear, and radiation physics.

What is the erg unit used for?

The erg is a CGS unit of energy used to quantify mechanical, thermal, or electromagnetic energy, particularly in astrophysics and classical physics.

Why convert keV to erg?

Converting keV to erg helps compare atomic-scale energies with energies expressed in the classical CGS system, facilitating research in physics and astrophysics.
