A joule is the SI derived unit of energy, representing the energy transferred when a force of one newton moves an object one meter; it is also equal to one watt-second.

What is a kiloelectron-volt (keV)?

A kiloelectron-volt equals 1,000 electronvolts and is used to express energies of particles and photons at the atomic scale, commonly in physics and medical imaging.

Why convert joules to kiloelectron-volts?

Because keV units are more suitable for expressing atomic and nuclear scale energies, this conversion helps interpret energies of particles, photons, and electron transitions.
