What is a kiloelectron-volt (keV)?

A kiloelectron-volt is a unit of energy equal to 1,000 electronvolts, commonly used in atomic and nuclear physics to measure energies of particles and photons at atomic scales.

Why is the thermochemical calorie used in this conversion?

The thermochemical calorie is used because it offers a fixed, reproducible energy unit useful in historical thermochemical data and for expressing heat values in older literature.

Can this conversion be used for modern heat measurements?

While it can convert values, the joule is preferred in modern practice; calorie (th) conversions are primarily relevant when working with historical data or older references.
