Computing formula of round steel weight per meter:
Weight=Density x volume. Density of pure steel: 7.8g/cm³. Volume=Bottom area X height. Bottom area= 3.14 x the square of radius (screw steel and round steel share the same radius). For example, in order to compute the weight of round steel with diameter D of 150 and thickness of 65 (height H), diameter 150mm and height 65mm shall be converted into centimeter at first, namely, 15cm and 6.5cm, then the weight is calculated with formula [(D/2)^2]*π*H*7.8, and the result is [(15/2)^2]*3.14*6.5*7.8=8954.89g, viz. 8.955kg.

Computing formula of weight of all kinds of angle steel per meter
Angle steel: Weight per meter=0.00785* (side width+ side width-side thickness)*side thickness
Flat steel: Weight per meter=0.00785*thickness*side width
Pipe: Weight per meter=0.02466*wall thickness*(outer diameter-wall thickness)
Plate: Weight per meter=7.85*thickness
Brass pipe: Weight per meter=0.02670*wall thickness*(outer diameter-wall thickness)
Copper pipe: Weight per meter=0.02796*wall thickness* (outer diameter-wall thickness)
Aluminum checkered plate: Weight per square meter=2.96* thickness
Specific density of nonferrous metal: Copper plate 8.9, brass plate 8.5, zinc plate 7.2 and lead plate 11.37
Computing formula of nonferrous metal plates: Weight per square meter=Specific density*thickness.
