The weight per square foot to any gauge can easily be obtained from the above Table by multiplying the weight of a square foot of the metal 1 inch thick by the thickness of the gauge in inches or parts of an inch.

1 Hutton's Works Manager's Handbook, where very useful Tables of the weight of iron according to this and the Imperial Standard Gauge are given.
