The values and units generated in equation (1.5) are accurate to the same degree as Wheeler's formula for inductance since it incorporates Wheeler's formula unchanged. The exact value of Cd is equal to:

I'm new at radio, so just for practise I tried to check the inductance of the coil Hue described: 42 turns on 2.5" diam. form, length 8". In searching the Web for formulas, I found two that give very different numbers.

John...An inductance formula for single-layer, solenoid type coils is as follows: Inductance in uH equals number of turns times coil radius in inches (quantity squared), divided by the quantity 9 times the radius plus 10 times the coil length, also in inches.

an introduction to the basic units of inductance, capacitance and resistance. ... Well mine did because I measured it on an inductance meter (see kits) operating at about 740 Khz. - [but compare that value with formula later]. ... Let's start out with the formula for the inductance for a straight piece of wire.

It can be used to find the self inductance of an air cored solenoid coil. The range of dimensions over which this equation can be accurately used is unclear, the book makes no mention of its limitations. The equation is originally expressed with imperial units but it is straightforward to convert these to metric if desired.
