What is an electron-volt used for?

Electron-volts describe energies at atomic, molecular, nuclear, and particle physics scales, such as photon energies and semiconductor properties.

Why use horsepower hour as a unit?

Horsepower hour measures mechanical energy output over time, often used for engines and motors within engineering and legacy unit contexts.

Can I convert small electron-volt values to horsepower hours easily?

Small electron-volt values convert to extremely small horsepower hour amounts due to the large difference in energy scales.
