Joules to eV Calculator: Convert Energy Units Accurately

In the realm of physics and engineering, the conversion between joules (J) and electronvolts (eV) is crucial for understanding energy levels and electron behavior. This conversion is particularly relevant in fields such as atomic and nuclear physics, electronics, and material science.

Joule: The SI Unit of Energy

The joule (J) is the derived unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter. One joule is equal to one watt-second.

Electronvolt: Energy of an Electron

The electronvolt (eV) is a unit of energy that represents the energy gained or lost by an electron when it moves through an electric potential difference of one volt. One electronvolt is equal to 1.602176634 × 10^-19 joules.

Conversion Formula: Joules to eV

The conversion formula from joules (J) to electronvolts (eV) is given by:

eV = J / (1.602176634 × 10^-19)
