P.I.W.  (Pounds Per Inch of Width):

Weight of coil ÷ by Width of coil = P.I.W.

Approximate Weight of Sheet/Plate:

Width x Length x Nominal Gauge x .2833 = Weight of Sheet

Approximate Average Gauge of Coil:

Weight ÷ .2833 ÷ Width ÷Linear Footage ÷ 12  = Average Gauge

**.2833 = density of mild carbon steel
