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.
