AND DECIMAL PARTS; THE THICKNESS BEING MEASURED BY THE NEW IMPERIAL STANDARD WIRE-Gauge. Sheet-Copper weighs approximately ounce per For kilogrammes per square m-tre, divide the weight of copper in pounds per square foot by 205. = inch per square foot. Therefore to find the weight of sheet-copper when in stated decimals of an inch, subtract onefourth of the number of thousands of an inch. For instance, the weight of a sheet of copper 064 inch thick is 064 ÷ 4 = '016, and 064 - 016 48 ounces per square foot. To find the thickness in thousands of an inch, add one-third to the number of ounces per square foot. For instance, the thickness of a plate weighing 48 ounces per square foot is = 48316, and 48 + 16 = 64, and = '064 thousands. = 1.38 I'21 1'04 O'95 |
