Steel is ordered by weight but counted in pieces. Read the standard weights off the chart, or work out your own quantity below — any diameter from 8 mm to 40 mm.

You know the tonnage on the drawing. Find out how many bars that is.
Figures are indicative, calculated on the standard d² ÷ 162 formula used with IS 1786 bars. Actual delivered weight varies slightly by mill and by rolling tolerance, so treat this as a planning aid rather than a billing figure. We'll confirm exact weights when we quote.
The numbers most people are actually looking for. A standard bar runs 12 metres.
| Diameter | Weight per metre | Weight per 12 m bar | Bars per tonne (12 m) |
|---|---|---|---|
| 8 mm | 0.395 kg | 4.74 kg | 210 |
| 10 mm | 0.617 kg | 7.41 kg | 135 |
| 12 mm | 0.889 kg | 10.67 kg | 93 |
| 16 mm | 1.580 kg | 18.96 kg | 52 |
| 20 mm | 2.469 kg | 29.63 kg | 33 |
| 25 mm | 3.858 kg | 46.30 kg | 21 |
| 32 mm | 6.321 kg | 75.85 kg | 13 |
| 40 mm | 9.877 kg | 118.52 kg | 8 |
Bars-per-tonne is rounded down, so ordering to that figure leaves you slightly under a tonne rather than over.
