## How to Convert Volts to Joules

*Volts* are a measure of voltage while *coulombs* measure electric charge. Together, these measurements can be used to find the energy in joules using a formula.

### Volts to Joules Formula

The formula to convert volts to joules is:

E_{(J)} = V_{(V)} × Q_{(C)}

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

**For example,** let’s convert a charge of 4 coulombs at 12 volts to joules.

E_{(J)} = 12 V × 4 C

E_{(J)} = 48 J

So, a charge of 4 coulombs at 12 volts is equal to 48 joules of energy.
