What is an electron-volt (eV)?

An electron-volt is the energy gained by an electron when it moves through an electric potential difference of one volt, equal to exactly 1.602176634×10⁻¹⁹ joule.

Why convert electron-volts to calorie (th)?

Conversion helps relate atomic or nuclear energy measurements to older thermochemical heat units found in historical calorimetry and thermochemical literature.

Is calorie (th) still used in science?

While calorie (th) is largely replaced by the SI joule, it remains relevant for interpreting historical thermochemical data and older educational resources.
