# Joules to electron-volts conversion

Joules to electron-volts (eV) conversion is the process of converting energy values from joules (J) to electron-volts. To convert joules to electron-volts, you need to divide the value in joules by the elementary charge, which is approximately 1.602 x 10^-19 coulombs.

## What is Joules to electron-volts conversion

To convert joules (J) to electron-volts (eV), you can use the conversion factor 6.242 × 10^18.

Electron-volts = J * 6.242 × 10^18

For example, let's convert 1 joule to electron-volts:

Electron-volts = 1 J * 6.242 × 10^18 Electron-volts ≈ 6.242 × 10^18 eV

Therefore, 1 joule is approximately equal to 6.242 × 10^18 electron-volts.

## How to convert joules to eV

One joule is equal to 6.241509⋅10^{18} electron-volts:

1J = 6.241509e18 eV = 6.241509⋅10^{18 }eV

So the energy in electron-volts *E*_{(eV)} is equal to the energy in joules *E*_{(J) }times 6.241509⋅10^{18}:

*E*_{(eV)} = *E*_{(J)} × 6.241509⋅10^{18}
