Calculate TMT bar weight (8mm to 32mm) for Pakistani construction. Per meter, per foot, total, and cost — instant results.
Total Steel Weight
(0 tons)
Formula: Weight (kg/m) = D² ÷ 162.28, where D is diameter in mm. Standard density: 7850 kg/m³.

| Diameter (mm) | Weight per Meter (kg) | Weight per Foot (kg) | Cost/m @ Rs 290/kg |
|---|---|---|---|
| 8mm | 0.395 | 0.121 | ~Rs 115 |
| 10mm | 0.617 | 0.188 | ~Rs 179 |
| 12mm | 0.888 | 0.271 | ~Rs 258 |
| 16mm | 1.578 | 0.481 | ~Rs 458 |
| 20mm | 2.466 | 0.751 | ~Rs 715 |
| 25mm | 3.853 | 1.174 | ~Rs 1,117 |
| 32mm | 6.313 | 1.924 | ~Rs 1,831 |
| Grade | Price per Ton (PKR) | Price per kg | Best For |
|---|---|---|---|
| Grade 60 TMT | 275,000 — 320,000 | Rs 275-320 | Standard residential + commercial |
| Grade 40 (Mild) | 240,000 — 270,000 | Rs 240-270 | Non-load-bearing, economy |
| Premium Brands (Mughal, Amreli) | 290,000 — 330,000 | Rs 290-330 | Premium projects, large spans |

Standard formula: Weight (kg/m) = D² ÷ 162.28, where D is the bar diameter in millimeters. This works for round bars including TMT and mild steel. For 12mm: 12² ÷ 162.28 = 0.888 kg/m.
Grade 60 TMT is the modern standard — high strength (60,000 psi yield), suitable for earthquake-prone areas, used in 95%+ of Pakistani residential construction. Grade 40 is older mild steel — lower strength, used in non-load-bearing applications or budget projects.
Approximate steel requirements: 3-4 tons for a single-story 5 marla house, 6-8 tons for double-story. Exact quantity depends on structural design, slab thickness, column count, and seismic considerations. Use our 5 marla cost calculator for complete material estimates.
Top brands by quality and consistency: Mughal Steel, Amreli Steels, Ittefaq Steel, Naveena Steel, Kamran Steel. All produce Grade 60 TMT bars meeting Pakistani standards. Mughal and Amreli are premium choices. Check PSQCA (Pakistan Standards Quality Control Authority) certification.
Standard length: 40 feet (~12 meters). Some suppliers cut to 30, 36, or 60 feet on request. Most construction sites order 40-foot bars and cut on-site as needed.
The formula gives theoretical weight ±2%. Actual weights vary slightly by manufacturer due to rolling tolerances. Always verify with supplier weights for bulk purchases. For project estimates, this calculator is reliable.
