Joule (J) is the unit of energy which is used by the International Standard of Units (SI). It is defined as the amount of work done by a 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. Following steps will help you to get 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 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.
