## How to convert joules to electron volts (J to eV)

The formula for converting joules to electron volts is: eV = J × 6241509074461000000. To calculate the joule value in electron volts first substitute the joule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 joule in electron volts we follow these steps:

eV = J × 6241509074461000000

eV = 1 × 6241509074461000000

eV = 6241509074461000000

In other words, 1 joule is equal to 6241509074461000000 electron volts.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 joules to electron volts is:

- Understand the conversion formula: eV = J × 6241509074461000000
- Substitute the required value. In this case we substitute 5 for J so the formula becomes: eV = 5 × 6241509074461000000
- Calculate the result using the provided values. In our example the result is: 5 × 6241509074461000000 = 3.1207545372305e+19 eV

In summary, 5 joules is equal to 3.1207545372305e+19 electron volts.

## Converting electron volts to joules

In order to convert the other way around i.e. electron volts to joules, you would use the following formula: J = eV × 1.602176487e-19. To convert electron volts to joules first substitute the electron volt value into the above formula, and then execute the calculation. If we wanted to calculate 1 electron volt in joules we follow these steps:

J = eV × 1.602176487e-19

J = 1 × 1.602176487e-19

J = 0.0000000000000000001602176487

Or in other words, 1 electron volt is equal to 0.0000000000000000001602176487 joules.

## Conversion Unit Definitions

### What is a Joule?

^{2}/s

^{2}in terms of mass, length, and time.

### What is a Electron Volt?

^{−19}joules. The electron volt is a very small unit of energy, but it is convenient for describing atomic and subatomic processes because the energies involved at the atomic and molecular scale are typically quite small.
