What is an electron-volt (eV)?

An electron-volt is the energy an electron gains when accelerated through a potential difference of one volt, used to express energies at atomic and particle physics scales.

How many electron-volts are in one kiloelectron-volt?

One kiloelectron-volt equals 1,000 electron-volts.

Why convert from eV to keV?

Converting to kiloelectron-volts simplifies representation of larger energy values, making it easier to communicate and analyze data in fields like nuclear physics and medical imaging.
