What does one electron-volt represent?

One electron-volt is the energy gained by an electron accelerated through a potential difference of one volt, equal exactly to 1.602176634×10⁻¹⁹ joule.

Are newton meters used only for energy measurements?

No, newton meters measure mechanical work or energy and also commonly represent torque, which is an application requiring careful differentiation.

Why convert electron-volts to newton meters?

Converting eV to N·m helps express atomic-scale energy in mechanical or engineering terms where standardized mechanical units are preferred.
