Joule (J) is the unit of energy that is used by the International Standard of Units (SI). It is defined as the amount of work done by the force of one Newton acting on an object that moves over a distance of one meter. It is additionally the energy dissipated as heat when an electrical current of 1 ampere passes through a resistance of 1 ohm for one second.

One V is defined as the difference in electric potential between 2 points of wire once an electrical current of 1 ampere dissipates one watt of power between those points.

It is a simple online calculator. The following steps will help you to get the result-

1) Enter the energy in Joules.

2) Enter charge in Coulombs.

3) Click on the calculate tab for the result.

V (V) = E (in Joule) / Q (in coulombs)

Using the above formula, you’ll be able to define the voltage (in volts) is equivalent to the energy E (in joules), divided by the charge Q (in coulombs).

So that you can rewrite the formula like this:

volt (V) = joule(J) / coulomb(C)

Or

V = J / C

The coulomb (C) is the standard unit of electric current/charge in the International System of Units (SI).

Coulomb is a dimensionless quantity, like a mole.

1 C is approximately equal to 6.24 x 1018 or 6.24 quintillion.
