Re: Magnet Wire



page 547 of a 1953 radio amateur's handbook has a table of copper wire info
for #22, it says 25.35 mils diameter, or .6438 mm
642.4 circular mils area
37 turns per liniear inch with enamel insulation
514.2 feet per pound, bare, or 461 feet per pound with DCC (douldble cotton
coated)
nearest british wire gauge is 23 SWG

so I think your calculations must be wrong.

32 gauge has5227 ft per pound (closer to your estimate)
