WEIGHT FORMULAS

For Aluminum Products

Round Rod: Square of diameter x 9.42 x density of alloy (Ibs. per cubic inch) = weight per lineal foot in pounds.

Square Bar: Square of one side x 12 x density of alloy (Ibs. per cubic inch) = weight per lineal foot in pounds.

Hexagon Rod: Square of distance across flats x 10.4 x density of alloy (Ibs. per cubic inch) = weight per lineal foot

Rectangular Bar: Thickness x width x 12 x density of alloy (Ibs. per cubic inch) = weight per lineal foot in pounds.

Round Tube: 37.7 x density of alloy (Ibs. per cubic inch) x wall thickness x outside diameter minus wall thickness = weight per lineal foot in pounds.

Square Tube: 1.27 x the weight of a round tube of the same wall thickness, and of diameter equal to the distance across the flats of the square tube = weight per lineal foot

Sheets: Thickness x 144 x density of alloy (Ibs. per cubic inch) = weight per square foot in pounds.

Strips and Rolls: Thickness x width x 12 x density of alloy (Ibs. per cubic inch) = weight per lineal foot in pounds.

Circles: Square of diameter x thickness x 0.785 x density of alloy (Ibs. per cubic inch) = weight of a circle.

Rings: Outside diameter plus inside diameter x outside diameter minus inside diameter x thickness x 0.785 x density of alloy (Ibs. per cubic inch) = weight of ring in pounds.
