FIGURE 158.
WIRE AND SHEET METAL GAGES IN INCH EQUIVALENTS.
(b) Brown & Sharpe (B&S) or American Wire Gaging System (AWG).
This gaging system is used for copper, copper alloy, aluminum, magnesium,
nickel alloy, and other nonferrous metal wires used commercially.
(3) Rod Gaging Systems. The Brown & Sharpe gaging system is used for
copper, brass, and aluminum rods.
Steel rods are nominally listed in
fractional sizes, but drill rods may be listed in Stubs steel wire gage or
the twist drill and steel wire gage.
It is preferable to refer to twist
drill sizes in inch equivalents rather than by the Stubs or twist drill
numbers.
d. Standards of Weight. The two most commonly used standards of weight
are the Metric and English weight measures.
