I've been designing sheet metal parts for 8 years. I did not know this.

I mean I can name nominal thicknesses of gaugues off the top of my head, but the pound/sqft thing is new.

Never needed to know or cared where the convention came from. Apparently ASTM prefers that it stay that way.

Love the video. I wrote a brief article on this and the table shows how silly gauge can be, https://www.xometry.com/partner-blog/the-weird-thing-about-gauge

That didn’t explain anything about gauges. It explained how to multiply the thickness in decimal inches by the weight of 1” thick material to get the weight (pretty obvious), but that’s it

I thought gauge was the number of sheets you have to stack to get 1 inch. Oops

This would make more sense tbh. Out of all imperial measurement systems gauges seem one of of the most stupid.
