Why is it called gauge? why not mm, cm, etc?

The number of the gauge size corresponds to a fraction of a centimeter divided by that number. For example, gauge 20 needle is 1 cm dived by twenty, or 0.5 mm. And for a gauge 26 needle, the diameter of the needle is 0.385 mm. That means as the gauge increases, the needle becomes smaller. I guess they use gauges rather than the actual needle size because it's easier to say "gauge 20" rather than "0.5 mm."

Why do trains run on a gauged track?
Gauge how far something is lately?
Gotta have some way to measure things.
Especially things that are fractions of inches.
Mils, mms, iotas, microns, A.U.s.
Just a name that someone, somewhere applied one time and it stuck. No rhyme or reason. It's just what they call it.
