1. Formula for rebar weight calculation:

Formula: diameter mm × diameter mm × 0.00617 × length m

Example: Rebar Φ20mm (diameter) × 12m (length)

Calculation: 20 × 20 × 0.00617 × 12 = 29.616kg

2. Steel tube weight calculation formula

Formula: (outer diameter-wall thickness) × wall thickness mm × 0.02466 × length m

Example: 114mm (outer diameter) x 4mm (wall thickness) x 6m (length)

Calculation: (114-4) × 4 × 0.02466 × 6 = 65.102kg

3. 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

4. Calculation formula of square steel weight

Formula: side width (mm) x side width (mm) x length (m) x 0.00785

Example: Square steel 50mm (edge width) × 6m (length)

Calculation: 50 × 50 × 6 × 0.00785 = 117.75 (kg)

5. Flat steel weight calculation formula

Formula: side width (mm) x thickness (mm) x length (m) x 0.00785

Example: Flat steel 50mm (edge width) x 5.0mm (thickness) x 6m (length)
