Good question -

Same is true with IV catheters - The smaller the gauge, the bigger the hole it puts in ya...

American wire gauge
American wire gauge (AWG), also known as the "Brown and Sharpe" wire gauge, is used in the United States and other countries as a standard method of denoting wire diameter, especially for nonferrous, electrically conducting wire. The steel industry uses a different numbering system for their wire thickness gages (e.g. W&M Wire Gage or US Steel Wire Gage or the different Music Wire Gage) so data below does not apply to steel wire. A wire is a single, usually cylindrical, elongated strand of drawn metal. ... Lightning strikes during a night-time thunderstorm. ... Electrical conduction is the movement of electrically charged particles through matter. ...


Increasing gauge numbers give decreasing wire diameters, which is similar to many other non-metric gauging systems. This seemingly-counterintuitive numbering is derived from the fact that the 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 does 0 gauge wire.

A die is a tool used in the manufacturing industry to create a wide variety of products and components. ...


Note that for gauges 5 through about 14, the wire gauge is effectively the number of bare solid wires that, when placed side by side, span 1 inch. That is, 8 gauge is about 1/8" in diameter.


In the same fashion, AWG is also commonly used to specify body piercing jewelry sizes, especially smaller sizes.[1] A bead ring, also known as a captive bead ring. ...

Like they say, "If it's on the internet, it's gotta be true!"

:sqwink:
 
I was always under the impression that the AWG number stood for resistance per so many feet of wire. The smaller the wire the greater the resistance, the larger the wire is the smaller amount of resistance it has.

I learned this from my dad back in the 60's but I could have remembered what he said wrong or maybe he just wasn't as smart as I thought he was!
 
Did a little search on the internet and found some material including the formula used to determine the AWG size.

So it appears that Dad was wrong (in part)

AWG is related to diameter of the wire, however diameter has a direct relation to the resistance of the same.
