Metal gauge?

My brother in-law says that the gauge of metal is equal to the quantity it takes to make one inch. So 18 gauge metal would equal 18 pieces stacked to make one inch and 20 gauge would be 20 pieces to make one inch. Is this true? Thanks, Tom

Not true. Different sheet metals such as mild steel, aluminum, stainless & galvanized measure different thicknesses of the same gauge.

Mild steel 10 gauge measures 0.1345. If you multiply that by 10 you get 1.345".

I think the math proves it out, but 3 seconds on Google and this was the first hit...

No. I don't believe it. 10 gauge is 1/10 of an inch and 1 gauge is an inch thick. Which is not the case.

So why is a 10Guage a bigger gun than a 12Guage?

For shotguns: The gauge number is determined by the weight, in fractions of a pound, of a solid sphere of lead with a diameter equal to the inside diameter of the barrel. So, a 10 gauge shotgun nominally should have an inside diameter equal to that of a sphere made from one-tenth of a pound of lead. A 12 gauge would be the diameter of a sphere made from one-twelfth of a pound of lead.

Same reason 10ga. steel is thicker than 12ga. steel. It's not based on the larger number being the thicker or larger caliber.

16ga is 1/16" thick. Thats all I remember and just adjust from there for thicker or thinner metal.

If it's plain steel it's close, but not galvanized or aluminum.
