Gage and Inch
Gage and Inch
(OP)
Is there any relationship between gage (16 gage or 14 gage etc.) and inch thickness?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

I guess, my question is how do you define gage in terms of inch or mm?
BTW, JKW05, thanks for the link. This is very useful.

There is no mathematical correlation between gauge numbers and thickness but apparently there is a correlation between thickness and the density of 41.82 pounds per square foot per inch of thickness per Machinery's Handbook.
SSMA's thickness chart expresses the minimum thickness in terms of mils (one thousandths of an inch) which is approximately 95% of the design thickness. The design thickness as approximately 95% of the actual thickness based on the 41.82 psf/in.

I always thought that 1/4 inch was 4 gauge (imperial) & every change of 6 gauges doubled or halved the thickness.
4 g was 1/4 inch
10 g was 1/8 inch
16 g was 1/16 inch
22 g was 1/32 inch
I just did a google & found out that this rule is only roughly correct - but OK for an empirical relationship (in the workshop with no reference books).
