What is a joule used for?

A joule is the SI derived unit of energy used for measuring work, heat, and mechanical or electrical energy, such as lifting objects or powering devices.

Why convert joules to electron-volts?

Converting to electron-volts helps compare classical energy quantities with atomic and particle physics energy scales, essential in research and semiconductor analysis.

Is electron-volt suitable for everyday energy measurements?

No, electron-volts are very small units best suited for atomic-scale energies rather than everyday mechanical energy.
