To calculate the inductance of an real life inductor, build the circuit using a capacitor, resistor and any square wave generator ( might be a microcontroller or 555) with 100+ Hz ,measure the pulses' frequency or period and use the following formula. L = 1/( f^2 * 4 * π ^2 * C ). This is useful if you have a osciloscope because you may see the input response of the tank LC circuit and measure its period/freqiency.
Note: the EveryCircuit frequency measuring has better precision for lower time stamps ( < ms/s )
