What is a microjoule (µJ)?

A microjoule is one millionth of a joule and measures very small amounts of energy, often used in scientific and engineering contexts.

What does a kiloelectron-volt (keV) represent?

A kiloelectron-volt equals 1,000 electronvolts and is used to express energies of particles and photons at the atomic and nuclear scale.

Why convert microjoules to kiloelectron-volts?

Converting microjoules to kiloelectron-volts helps translate small macroscopic energies into atomic-scale units relevant in physics, spectroscopy, and medical imaging.
