A 500 gauge polythene sheet is approximately 0.125 millimeters thick. The thickness is derived from the standard conversion where 1 gauge is equal to 0.254 millimeters. Therefore, 500 gauge translates to 500 x 0.254 mm, resulting in a thickness of about 127 millimeters, which is often rounded to 0.125 mm for practical purposes.
4mm sheet metal falls 24 gauge and 25 gauge. 24 gauge sheet metal is 3.175mm (0.125") thick, and 25 gauge sheet metal is 6.35 (0.25") mm thick.

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...
There's a conversion table at this website which will tell you. http://www.mesteel.com/info/carbon/thickness.htm

Probably 25 gauge, which is .556 mm thick. However, 26 gauge is close too, it is .478 mm thick.

No. The larger the number, the thinner the steel. 16 gauge is the thicker of the two.

Both 31 and 32 gauge are close:31 gauge = 0.0105"32 gauge = 0.0097"
16 gauge what? Wire... sheet metal... shotgun? No, seriously; look up a guage thickness chart for the material in question.
Her is a link to a chart of all guages... http:/www.unc.edu/~rowlett/units/scales/sheetmetal.html #26 wire is .0159 thousandth of an inch or .405 mm in diameter. This is for AWG wire sizes which is different from the steel industry which use a different numbering system for their wire thickness gauges.
