.0500 inches or 1.27 mm
18 gauge solid copper wire is 40.3 mils in diameter, that is 0.0403" stranded would be larger.
It is thicker than 1/8th inch thick steel.
Between 6 and 7 gauge. 6 is thicker at .194 inch. 7 is thinner at .179 inch.
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...
3/16" or 0.1875" *** 7 gauge steel sheet is .1793", not .1875" *** Different metals have different thickness for their gauge...mild steel is .1793, aluminum is .1443, stainless steel is .1875
Pipe and sheet metal of various types use different scales. For 14 gauge metal, the thicknesses would be (in inches): 0.0781 inches - US Standard Gauge 0.0747 inches - Sheet Steel 0.079 inches - Galvanized Steel 0.0781 inches - Stainless Steel 0.083 inches - Tubing Thus, 14 gauge pipe would nominally be 0.083 inches thick.
A 21 Gage Steel plate is about 1/32 inch thick. Various charts put it at .032" to .033". That is for plain steel. Galvanized, aluminum and stainless have different measurements for the same gage.
16 gauge
.1250 inches or 3.18 mm
17/64ths of an inch for steel
14G
Standard steel thickness 0.0179 of an inch. Galvanised steel is 0.0217 of an inch and aluminium 0.0159 of an inch
