Why is it the only SUPERPOWER country keep using AWG ?
Then i did see this https://www.eevblog.com/forum/beginners/how-to-meassure-awg/?topicseen Why not just give in to the meter system like us that already did see the light
Back in the day,in Oz,we had to contend with both AWG (we called it B&S),& SWG,which was the Brit gauge standard.
They were not very compatible,& conversion charts were few & far between.
Of course,wire companies had the charts,& transformer winders,but the rest of us were battling.
Micrometers were rare,as they were expensive,so direct measurement was usually out of the question.
The standard trick,if you had a sample of both which looked pretty similar,was to wind,say.10-20 turns on a round former,& measure the length occupied by the winding.
If it was close,you could say it was near enough.
Most hobbyists just guessed!
We also had the delights of Brit stuff with BSF,and/or Whitworth.and/or UNF bolts,plus BA screws,often all in the same piece of equipment!
Small screws in German equipment used very fine threads which were in no way compatible with the equally metric threads used in Japanese stuff.
Then there were the American screws,which,although nominally Imperial,bore no resemblance to Whitworth/UNC.or SAE/UNF.
You always lost one,& they were unobtainium!!
I nearly lost a couple off my Tektronix 7613 yesterday!!
