An electron-volt (eV) is a unit of energy commonly used in atomic, nuclear, and particle physics. It is defined as the amount of kinetic energy gained by a single electron when it accelerates through an electric potential difference of one volt.
A volt (V) is the derived unit for electric potential, electric potential difference, and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta.
The conversion between electron-volts and volts is based on the elementary charge:
\[1 \text{ eV} = 1.602176634 \times 10^{-19} \text{ V}\]This means that to convert from eV to V, we multiply the number of electron-volts by this conversion factor.
This conversion is particularly useful in various fields of physics and chemistry, including:
Understanding the relationship between electron-volts and volts helps scientists and engineers work with energy scales relevant to atomic and subatomic phenomena.
