Steel Weight Calculation Formulas
Weight = Volume × Density (7850 kg/m³ for mild steel)
⚪ Round Bar / Rebar
Volume = π × (Diameter/2)² × Length
🔘 Pipe / Tube (Hollow)
Volume = [π × (OD/2)² - π × (ID/2)²] × Length where ID = OD - (2 × Wall Thickness)
🔲 Square Bar / Hollow Section
Volume = (Width × Height - Inner Area) × Length (Inner Area = 0 for solid bars)
📄 Plate / Sheet
Volume = Length × Width × Thickness

Frequently Asked Questions
What is the density of steel used in this calculator?
This calculator uses the standard density for mild steel: 7850 kg/m³ (or 490 lbs/ft³).
How to calculate weight of TMT bars?
Select "Round Bar" as the shape, enter the bar diameter (e.g., 10mm, 12mm, 16mm) and total length.
Is this calculator free?
Yes, from Alpando Toolbox, it's 100% free with unlimited calculations.
💡 Pro Tip from Alpando Toolbox:
For accurate cost estimation, always add 5-10% for wastage when ordering steel. Use the quantity field to calculate total weight for multiple pieces. For TMT bars, remember that 1 ton = 1000 kgs — this calculator helps you convert length to weight quickly.
