7/64ths of an inch, or .109375 inches, or 2.77 mm.
Metal gauge is inversely proportional to thickness, the bigger the thickness lesser the gauge. Following is conversion table:- 10 G : 3.15 MM 11 G : 2.8 MM 12 G : 2.5 MM etc....
A 100 gauge piece of aluminum has a thickness of 0.0010 inches. Gauge is a universal system used to measure the thickness of metal and wire.
12 gauge is thicker than 14 gauge.
The 12-gauge is thicker.
The gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.
12 gauge is thicker than 20 gauge. The lower the gauge, the thicker the sheet metal or wire.
12 gauge vs. 14 gauge metal
GAUGE , is one inch thick of steel or metal. So, take this one inch thick of steel sheet and cut it into 12 equal thickness sheets , you get a 12 gauge steel sheet. Similarly, take this one inch thick of steel sheet and cut it into 14 equal thickness sheets , you get a 14 gauge steel sheet. and so on . So, a 12 gauge steel sheet is thicker than 14 gauge , 14 is thicker than 16 , 16 is thicker than 18 and so on. Wrong!!! See my discussion on this...
The lower the gauge the heavier, sheet metal, wire & shotguns...

The concept of the gauge originated with pistols, and later shotguns. The gauge described the size of the barrel by the fraction of a pound of a round iron ball that just fits the barrel. For example, a 12 guage shotgun has a barrel that will just fit a round iron ball that is one twelfth of a pound. This measurement stemmed from cannon measurements, which measured the cannon by the size of the cannon ball it fired (such as a 6 pound cannon, or 20 pound cannon). There are different gauges that describe thickness, including the American Wire Gauge that measures the thickness (diameter) of electrical wire, US Steel Wire Gauge for steel wire, Sheet Metal Gauge, etc.
