Relation Between Electronvolt (ev) and Joule (J)
Let me explain to you about the relation between Electronvolt ev and Joule (J) first before moving to the conversion process. Because it’s essential to grasp what these units represent.What is Electronvolt (ev)?
An electronvolt is the amount of kinetic energy gained by an electron when it accelerates through an electric potential difference of one volt. 1 Electronvolt (ev) is a unit of energy measurement which is commonly used in Particle Physics, Energy. Electronvolts are commonly used in atomic and nuclear physics to measure the energy of particles and the energy levels of atoms and molecules..What is Joule (J)?
Electronvolt (ev) is another unit of energy measurement that is used in Physics, Energy. The joule is the SI unit of energy, defined as the amount of work done when a force of one newton is applied over a distance of one meter. 2 . Electronvolts are commonly used in atomic and nuclear physics to measure the energy of particles and the energy levels of atoms and molecules..How to Convert Joule (J)?
The conversion between Electronvolt (ev) and Joule (J) follows a simple formula:Electronvolt = Electronvolt × 1.602176634e-19
Where, 1.602176634e-19 is the value that allows you to convert between Electronvolt (ev) and Joule (J).
So,
1 Joule = 1.602176634e-19 Electronvolt
And, 1 Electronvolt = 1/1.602176634e-19 Joule

Examples of Converting Electronvolt (ev) to Joule (J)
To convert any value from Electronvolt (ev) to Joule (J), simply multiply the amount of Electronvolt (ev) by the conversion factor:1 Joule = 1.602176634e-19 Electronvolt
For example, if you want to convert 5 Electronvolt into Joule and the conversion factor is 1.602176634e-19, then:
5 Electronvolt = 5 x 1.602176634e-19 Joule
