What is a kilojoule used for?

A kilojoule (kJ) is used to measure energy in contexts like nutrition, chemical thermodynamics, and engineering, representing macroscopic energy quantities.

Why convert kilojoules to megaelectron-volts?

Converting kilojoules to megaelectron-volts helps translate macroscopic energies into atomic or subatomic scales, useful in nuclear physics and particle physics research.

Are these conversions practical for everyday purposes?

No, because kilojoules and megaelectron-volts apply to vastly different physical scales, the conversion is mainly theoretical or for specialized scientific use.
