Conversion Formula
The conversion from ev to joules is based on the formula: Joules = ev * 1.602176634 x 10-19. This works because 1 ev is defined as the energy gained by an electron when it moves through a potential difference of 1 volt, which equals 1.602176634 x 10-19 joules.
For example, converting 5 ev involves: 5 * 1.602176634 x 10-19 = 8.01088317 x 10-19 joules.
Conversion Example
- Convert 10 ev to joules:
- – Step 1: Use the formula Joules = ev * 1.602176634 x 10-19.
- – Step 2: Multiply 10 by 1.602176634 x 10-19.
- – Step 3: 10 * 1.602176634 x 10-19 = 1.602176634 x 10-18 joules.
- – Therefore, 10 ev equals approximately 1.6022 x 10-18 joules.

Conversion FAQs
Why is the ev to joules conversion so small?
The ev to joules conversion results in very small numbers because an electron volt is a tiny amount of energy, suitable for atomic-scale measurements. The joule is a larger unit, so converting ev to joules naturally produces small values.
Can I use this conversion for other particles besides electrons?
While the conversion factor is based on the electron’s charge, similar calculations can be performed for other particles by considering their specific charge or energy levels, but the standard 1 ev equals 1.602176634 x 10-19 joules applies specifically to electrons.
What practical applications require converting ev to joules?
This conversion is essential in physics, chemistry, and electrical engineering when calculating energy at atomic or subatomic levels, such as in particle accelerators, quantum physics, and spectroscopy.
