**Online Joules (J) to volts (V) calculator.**

Use this Online tools for joules to volts conversion.Input the energy in joules(J), charge(Q) in coulombs and click the Calculate button to obtain Volts(V)

## How to convert energy in joules to electrical voltage in volts?

### Joules to volts Conversion formula

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

using above formula you can 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**

**Let’s take one example**

**Example#1**

Calculate the voltage supply in a circuit, which has energy utilization of 120 joules(J) and charges flow of 6 coulombs(C)

V = 120J / 6C = 20V
