Metric / American Standard gauges

[Fred Sturm]

Newton,
	Could you give a brief explication of each entry? I take it "size" is
equivalent to gauge, "Amer. inches" is the equivalent of that gauge in
inches from American suppliers, "metric inches" is what is supplied as
the given gauge by European suppliers (Roslau) measured in inches.
Beyond that, I'm a bit confused. Is "metric" the equivalent in
millimeters of "metric inches" and "Amer. metric" the equivalent in
millimeters of "Amer. inches"? 
	The remainder, I haven't a clue.
Thanks,
