What does one kiloelectron-volt represent?

One kiloelectron-volt is an energy unit equal to 1,000 electronvolts, used mainly to express particle and photon energies at the atomic scale.

What is a kilojoule used for?

A kilojoule is an SI-derived unit equal to 1,000 joules, typically used to quantify work, heat, and energy transfer in scientific and engineering fields.

Why do converted keV values appear very small when expressed in kJ?

Due to the large difference in scale between keV and kJ, conversion yields extremely small numerical values.
