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. |
