How to Convert eV to Joules?

One electron-volt is equal to 1,602176634⋅10-19 joules: 1eV = 1,602176634 ⋅10-19 J

The energy in joules E(J) can be determined by multiplying the energy in electron-volts E(eV) by the conversion factor of 1,602176634 * 10-19:

E(J) = E(eV) × 1,602176634 * 10-19.

Example

Let’s say we have an electron that has an energy of 5 electron-volts (5 eV). We want to convert this energy into joules.

The conversion factor between electron-volts and joules is 1 eV = 1.60218 x 10-19 J.

To convert 5 eV to joules, we can use the conversion factor:

5 eV * (1.60218 x 10-19 J/eV) = 8.0109 x 10-19 J

Therefore, 5 electron-volts is equivalent to 8.0109 x 10-19 joules.

Please note that the conversion factor provided is an approximate value and can vary slightly depending on the source and level of precision required.
