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
