Man, oh man. This is a complex issue. As a rresult, even though references may still be made to gauge, manufacturers purchase their metal according to decimal thickness.
Gauges, established years ago, have huge tolerance and interpretation of those tolerances can be very different from company to company.
Although it seems "simple" like I should be able to give you an equivalency chart, it isn't that simple because the chart may still not be an accurate representation of what a particular manufacturer is adhering to.
Your best bet is to actually inquire with individual roofing manufacturers as to thei decimal thickness of product they buy.
Remember, though, a lot more goes into the good performance of a metal roof than just base metal thickness. That is only one part, sometimes a minor part actually, of the overall picture.
