Please for the benefit of all us non US based readers, it would be great if posters us some sort of international units, metric would be best, inches is ok by me, gauge is not ok. I dont intend this to be the start of a flame war on metric versus inches, so I wont go into any such discussions. Henning
This may help you, gages are rounded to nearest .0000 of Inch.

Gauge measurements are often confusing even to folks in the USA. There are different gauges for different materials. Most folks don't know the difference. And I'll bet that most folks who are welding 16 gauge steel sheet don't even know the decimal inch equivalent. Some might be able to eyeball it to about 1/16". But I have have seen plenty of folks who would call it 1/8", 3/32" or even 1/32". So, I wouldn't rely on them posting in inches , much less SI units. Much better to do the conversion yourself and be correct.
I have included the metric equivalents for the US customary measures. Some of these are not metric standards, and there are some metric values that are not shown here. In metric, gage is given in millimetres.

conversion factor is .03937 for m/m to inches.
