Convert j to electron volt
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
Electron Volt
The electron volt (eV) is a unit of energy defined as the amount of kinetic energy gained by a single electron accelerating through an electric potential difference of one volt in vacuum. It is equal to approximately 1.602 × 10−19 joules. The electron volt is widely used in atomic, nuclear, and particle physics, as well as in solid-state physics and chemistry to express energies at the molecular and atomic scale.
