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

Steel Pipe weight 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

Flat steel weight 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 = 11.7.75 (kg)

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

Equal angle steel weight formula

Formula: side width mm × thickness × 0.015 × length m (rough calculation)

Example: Angle 50mm × 50mm × 5 thick × 6m (long)

Calculation: 50 × 5 × 0.015 × 6 = 22.5kg (table for 22.62)

Unequal angle steel weight formula

Formula: (side width + side width) × thick × 0.0076 × long m (rough calculation)

Example: Angle 100mm × 80mm × 8 thick × 6m (long)

Calculation: (100 + 80) × 8 × 0.0076 × 6 = 65.67kg (Table 65.676)
