Does anyone have a formula for calculating the AWG size of a wire from the
diameter (preferably in inches), and/or a formula for the number of turns per
inch based upon the AWG? I need these formulas for an excel spreadsheet so the
simpler they are the easier it is for me to put them in. They need to have
fairly good accuracy (+/- 1% or less). Also I haven't really looked around for
them yet, but if anyone has any formulas for inverse conical (saucer shaped)
primaries I could use those too.
