Converting from Joule (J) to Electronvolt (eV) | Energy

What is Joule (J)

Joule (J) is the standard unit of energy in the International System of Units (SI). It is used to quantify energy transfer, such as mechanical work. One joule is equal to the energy transferred when a force of one newton acts on an object over a distance of one meter.

What is Electronvolt (eV)

Electronvolt (eV) is a unit of energy commonly used in atomic and nuclear physics. It is the amount of kinetic energy gained by an electron when accelerated through an electrical potential difference of one volt. The electronvolt is often used in the realm of subatomic particles due to its convenient scale for measuring their energy.

Conversion Formulas

The conversion between Joule (J) and Electronvolt (eV) can be performed using the following formulas:
