shotgun gauge trivia
So then, how does the 00, 000, 0000 guages come into play, then? Is some operation done less than 0 times???

shotgun gauge trivia
This was prompted by a discussion of sheet steel gauge in another thread.
Most everyone knows that a 12 gauge shotgun has a larger barrel diameter than a 20 gauge, but who knows what the gauge description means? In other words, what physical size or object does 12 or 20 gauge refer to?
Answer in an hour if nobody posts it by then.

shotgun gauge trivia
Ok, it's been about an hour.
The gauge number is the number of lead balls you can make out of a pound of lead at that diameter. So using exactly 1 pound of lead you can make 12 balls with a diameter of about a dime or 12 gauge. 20 gauge gives you more but smaller lead balls. I think this comes from back in the day of large smoothbore muskets and later was used to designate shotgun diameters.
Is there an equivalent measure for sheet steel or wire diameter, or did someone just come up with those at random? This one I don't know.

shotgun gauge trivia
This is from Wikipedia
"gauge number is related to the number of drawing operations that must be used to produce a given gauge of wire; very fine wire (for example, 30 gauge) requires far more passes through the drawing dies than 0 gauge wire."
Most likely this is the case for steel thickness too, although I didn't find the precise info for sheet steel
