- enter the number of turns n, the coil diameter D and the wire diameter d, and the calculator will compute an estimated value of inductance L

- enter the coil diameter D, the wire diameter d and the inductance L, and the calculator will compute an estimated number of turns n

There is a good practise to wind 10% more turns than calculated. Any corrections will then be easier.
