📐 Shape Volume Formulas & Tips

⚪ Round Bar / Rod

Volume = π × r² × Length
Weight = (D²/162) × Length (for steel)

⬜ Square Bar

Volume = Side² × Length
Side in meters, Length in meters

📐 Rectangular Bar

Volume = Width × Height × Length

🔷 Hexagonal Bar

Volume = (2.598 × Side²) × Length
Side = distance across flat sides

🔘 Round Pipe / Tube

Volume = π × (OD² - ID²)/4 × Length
ID = OD - (2 × Wall Thickness)

📄 Plate / Sheet

Volume = Length × Width × Thickness

❓ Frequently Asked Questions

Q: How to calculate metal weight?

A: Metal weight = Volume × Density. Volume depends on shape, density varies by metal type. Use our calculator for instant results.

Q: What is the weight of 1 meter 12mm steel bar?

A: Using formula D²/162, a 12mm steel bar weighs 0.888 kg per meter.

Q: How to calculate pipe weight?

A: Pipe weight = π × (OD² - ID²)/4 × Length × Density. ID = OD - (2 × Wall Thickness).

Q: What is the density of mild steel?

A: Mild steel density is 7850 kg/m³ or 7.85 g/cm³.

Q: How to calculate aluminum weight?

A: Use same volume formula with aluminum density of 2700 kg/m³.
