Suppose you make your own hand-wound inductor. How do you measure inductance so you know what kinds of circuits it can be used in? Well, as it turns out, there is a clever trick you can use that involves using an oscilloscope to compare its output curves with a reference input curve at a sine wave frequency. Then once you determine the parameters of these curves, you can plug the numbers into some equations to calculate the inductance, in henrys (H). Typically, microhenrys.
