## How to Convert Joules to Volts

*Joules* are a measure of electrical energy and *coulombs* are a measure of charge. These measurements can be used to derive the voltage using this formula.

Volts = Joules ÷ Coulombs

Thus, the voltage is equal to the energy in joules divided by the charge in coulombs.

**For example,** let’s convert 20 joules and 5 coulombs to volts.

Volts = 20 J ÷ 5 C

Volts = 4 V
