# ELECTRON VOLT TO JOULES

As technology advances, we are becoming more and more dependent on electricity. To understand how electricity works, we often have to convert different units of measurement to make sense of it all. One common conversion that we need to know is how to convert electron volts to joules. In this article, we will explore what these units are and how to convert them.

What is an electron volt?

Electron volt (eV) is a unit of energy used in atomic physics and other fields of science. It is the amount of kinetic energy gained or lost by a single electron accelerating from rest through a potential difference of one volt in a vacuum. One electron volt is equivalent to 1.602 × 10^-19 joules.

What is a joule?

On the other hand, a joule (J) is the standard 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 equivalent to one watt-second or one kilogram-meters squared per second squared.

How to convert electron volts to joules?

To convert electron volts to joules, we simply need to multiply the number of electron volts by the conversion factor of 1.602 × 10^-19 joules. For example, to convert 100 eV to joules, we would use the following formula:

100 eV × 1.602 × 10^-19 J/eV = 1.602 × 10^-17 J

Therefore, 100 eV is equal to 1.602 × 10^-17 joules.

Conclusion

In conclusion, understanding the conversion of electron volts to joules is essential for various fields of science, especially for those who work with electricity. Remembering that one electron volt is equivalent to 1.602 × 10^-19 joules can make this conversion easier. By using this knowledge, we can ensure accurate calculations and have a better understanding of the energy concepts involved in our everyday lives.
