How to convert joules to volts

How to convert energy in joules (J) to electrical voltage in volts (V).

You can calculate volts from joules and coulombs, but you can't convert joules to volts since volt and joule units represent different quantities.

Joules to volts calculation formula

The voltage V in volts (V) is equal to the energy E in joules (J), divided by the charge Q in coulombs (C):

V(V) = E(J) / Q(C)

So

volt = joule / coulomb

or

V = J / C

Example

What is the voltage supply of an electrical circuit with energy consumption of 60 joules and charge flow of 4 coulombs?

V = 60J / 4C = 15V
