What is a kiloelectron-volt (keV)?

A kiloelectron-volt (keV) is an energy unit equal to 1,000 electronvolts and is used in atomic, nuclear, and radiation physics to express particle and photon energies at an atomic scale.

What does nanojoule (nJ) measure?

Nanojoule (nJ) is an SI-derived energy unit representing very small energy quantities, commonly used in laser pulses, microelectronics, and microdevice applications.

Why convert keV to nJ?

This conversion makes atomic-scale energy values practical for engineering and applied sciences, facilitating work in fields like laser technology and low-power electronics.
