Listing of Weight Formulas

 

  • ROUND ROD

    Square of diameter X 9.42 X density of alloy = weight per lineal foot in pounds.

  • SQUARE BAR

    Square of one side X 12 X density of alloy = weight per lineal foot in pounds.

  • HEXAGON ROD

    Square of distance across flats X 10.4 X density of alloy = weight per lineal foot.

  • RECTANGULAR BAR

    Thickness X width X 12 X density of alloy = weight per lineal foot in pounds.

  • ROUND TUBE

    37.7 X density of alloy 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.

  • SHEET

    Thickness X 144 X density of alloy = weight per square foot in pounds.

  • STRIPS AND ROLLS

    Thickness X width X 12 X density of alloy = weight per lineal foot in pounds.

  • CIRCLES

    Square of diameter X thickness X 0.785 X density of alloy = 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 = weight of ring in pounds.
