## How to Convert Joules to Volts

*Joules* are a measure of electrical energy dissipated to move a 1-kilogram object one meter using a constant force of one newton. *Coulombs* are the amount of charge accumulated in one second by a current of one ampere.

*Voltage* is the measure of the electric potential in an electric circuit to move an electric charge and is measured in volts.

You can convert joules to volts using these measurements using a formula.

### Joules to Volts Formula

To convert energy in joules to voltage in volts, use the formula below.

V_{(V)} = E_{(J)} / Q_{(C)}

Thus, the voltage *V* is equal to the energy *E* in joules divided by the charge *Q* in coulombs.

**For example,** let’s convert 20 joules of energy with a charge of 5 coulombs to volts.

V_{(V)} = 20 J / 5 C

V_{(V)} = 4 V
