No, although it would be a nice and simple way. If accuracy is important you
should also measure the frequency at which the dip for the L/C circuit occurs
(e.g. frequency counter or a general coverage receiver w/ digital dail).

You can also build a L/C tuned oscillator with a know amount of C. Install
a L, measure the frequency (see above) and calculate the value of L.

In either case the formula is L = (25330.3) / (F^2 x C)
