It is my understanding that a mil is a one thousandth of an inch (1mil = 0.001”). Also, a mil is 25.4 microns, aka micrometers. Then, it is my understanding that Gauge is 100x mil (1mil-100Ga).
I am looking for some copper sheets for a project, and I am confused. This Amazon listing:
Lists 0.0216" (inch) as a 24Ga (Gauge). How does that work? Am I reading the units wrong? 0.0216" = 21.6Mil = 2160Ga ? Is that right?
