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 to describe particle and photon energies.

Why convert kiloelectron-volts to joules?

Converting to joules provides a consistent standard SI unit of energy for use across various scientific and engineering applications.

Can this conversion be used for large scale energies?

No, kiloelectron-volts apply to particle-scale energies and should be converted to joules before attempting to represent larger energy quantities.
