Where? And in what context?The joule is the metric unit of energy and work. If you multiply a force (in newtons) by the distance (in inches) through which that force is applied, you can calculate the amount of work in joules that has been done.

But there are others ways to calculate energy or work. For example, the amount of electrical energy stored a capacitor is given by the expression E = [1/2]CV2, where C is the capacitance in farads and V is the voltage in volts. The result is in joules.
