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 this formula.

Joules = Volts × Coulombs

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

For example, let’s convert 12 volts and 4 coulombs to volts.

Joules = 12 V × 4 C
Joules = 48 J
