Multilayer coil inductance calculator:

The most of similar calculators work using Wheeler's formula, which has acceptable accuracy only when calculating the "optimal coil". Also, these calculators allow to calculate just a ready-made coil. This calculator allows to calculate the number of windings of the multilayer coil at the design stage. Inductance is calculated by accurate algorithm using Maxwell's equations with elliptic integrals, see more... You can select measurement units - mm or inches, and also AWG or SWG wire number - the wire diameter will be determined automatically.

Calculate number of turns

d   – Diameter of wire without insulation    
k   – Diameter of wire with insulation Automatic

Calculate
RESULT:
N – Number of turns
n – Number of Layers
c   – Winding thickness
Lw   – Required length of wire
Ω  Ohm – DC Resistance of coil

First Thank you for great effort for creating Nice and Easy Calculator.I have one doubt that for Square former the same calculation will apply or it differs.

You have to correct and pre-calculate dimensions for rectangular or square former. You can see how to do this in General Notes of Robert Weaver's calculator:

Is the multilayer coil calculator made considering the ferrite core ur=640 or just the air core coil?

This calculator designed only for multilayer air core coil with round form of turns.
