What is a kiloelectron-volt (keV)?

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

Why use calorie (IT) when joule is the standard?

Calorie (IT) is a historical unit mainly used in older thermodynamic data and steam-engine calculations, so it is useful for interpreting or converting legacy datasets.

When should I convert keV to calorie (IT)?

Convert keV to calorie (IT) when comparing atomic-scale energies with classical thermodynamic information or legacy engineering literature.
