Just curious about something. Is there a relationship between "gauge"

14-gauge wire the same thickness as 14-gauge metal sheet?

No, as Vic says, wire and thickness "gage" measurements are different
scales. To make it even more interesting, there are differing gage
scales as well (at least six in my Perry's).

What are the six in your Perry's? I can think of three:


Rather than being totally different applications, they're varying wire
and thickness standards most of which have proprietary backgrounds from
early manufacturing days before national/international standards were
common/established. There are relatively small differences (in absolute
terms) between these, but the differences can be significant in close
tolerance applications. For typical household wiring, the differences
are not significant.


1) wire diameter


- AWG or Brown & Sharpe (normally non-ferrous wire and sheet altho
footnote shows sometimes used for iron wire as well)

- US Steel Wire or Washburn&Moen or Roebling or Am. Steel&Wire
- Birmingham (BWG for steel wire) or Stubs Iron Wire
- Imperial Standard Wire Gage


2) steel thickness

- US Standard
- Standard Birmingham

I'm sure there are probably others--I didn't look at what are current
ISO standards, for example.


3) shot gun cartridge


Totally different scale and I don't have data at hand.

how about railroad gauge, is that in your book?

US standard gage is-- 4' 8-1/2". Don't have old narrow gage or other
such as British, etc.
