Formula for calculating the weight of various steels

Steel plate weight calculation formula
Formula: 7.85 × length (m) × width (m) × thickness (mm)
Example: Steel plate 6m (length) × 1.51m (width) × 9.75mm (thickness)
Calculation: 7.85 × 6 × 1.51 × 9.75 = 693.43kg
Steel pipe weight calculation formula
Formula: (outer diameter – wall thickness) × wall thickness mm × 0.02466 × length m
Example: steel pipe 114mm (outer diameter) × 4mm (wall thickness) × 6m (length)
Calculation: (114-4) × 4 × 0.02466 × 6 = 65.102kg
Round steel weight calculation formula
Formula: diameter (mm) × diameter (mm) × 0.00617 × length (m)
Example: round steel Φ20mm (diameter) × 6m (length)
Calculation: 20 × 20 × 0.00617 × 6 = 14.808kg
Square steel weight calculation formula
Formula: side width (mm) × side width (mm) × length (m) × 0.00785
Example: square steel 50mm (side width) × 6m (length)
Calculation: 50 × 50 × 6 × 0.00785 = 117.75 (kg)
Flat steel weight calculation formula
Formula: side width (mm) × thickness (mm) × length (m) × 0.00785
Example: flat steel 50mm (side width) × 5.0mm (thickness) × 6m (length)
Calculation: 50 × 5 × 6 × 0.00785 = 11.77.75 (kg)
Hexagon steel weight calculation formula
Formula: opposite side diameter × opposite side diameter × length (m) × 0.00068
Example: hexagonal steel 50mm (diameter) × 6m (length)
Calculation: 50 × 50 × 6 × 0.0068 = 102 (kg)
Rebar weight calculation formula
Formula: diameter mm × diameter mm × 0.00617 × length m
Example: Rebar Φ20mm (diameter) × 12m (length)
Calculation: 20 × 20 × 0.00617 × 12 = 29.616kg
Flat pass weight calculation formula
Formula: (edge length + side width) × 2 × thickness × 0.00785 × length m
Example: flat pass 100mm × 50mm × 5mm thick × 6m (long)
Calculation: (100+50)×2×5×0.00785×6=70.65kg
Square pass weight calculation formula
Formula: side width mm × 4 × thickness × 0.00785 × length m
Example: Fangtong 50mm × 5mm thick × 6m (long)
Calculation: 50 × 4 × 5 × 0.00785 × 6 = 47.1kg
Equal angle steel weight calculation formula
Formula: side width mm × thickness × 0.015 × length m (rough calculation)
Example: Angle steel 50mm × 50mm × 5 thickness × 6m (long)
Calculation: 50 × 5 × 0.015 × 6 = 22.5 kg (Table 22.62)
Unequal angle steel weight calculation formula
Formula: (edge width + side width) × thickness × 0.0076 × length m (rough calculation)
Example: Angle steel 100mm × 80mm × 8 thickness × 6m (long)
Calculation: (100+80) × 8 × 0.0076 × 6 = 65.67 kg (Table 65.676)
[Other non-ferrous metals]
Brass tube weight calculation formula
Formula: (outer diameter – wall thickness) × thickness × 0.0267 × length m
Example: brass tube 20mm × 1.5mm thick × 6m (long)
Calculation: (20-1.5) × 1.5 × 0.0267 × 6 = 4.446kg
Copper tube weight calculation formula
Formula: (outer diameter – wall thickness) × thickness × 0.02796 × length m
Example: copper tube 20mm × 1.5mm thick × 6m (long)
Calculation: (20-1.5) × 1.5 × 0.02796 × 6 = 4.655kg
Aluminum flower board weight calculation formula
Formula: length m × width m × thickness mm × 2.96
Example: aluminum flower board 1m wide × 3m long × 2.5mm thick
Calculation: 1 × 3 × 2.5 × 2.96 = 22.2 kg
Brass plate: specific gravity 8.5
Copper plate: specific gravity 8.9
Zinc plate: specific gravity 7.2
Lead plate: specific gravity 11.37
Calculation method: specific gravity × thickness = weight per square
