Sariya Weight Chart (IS 1786)

Sariya size	kg per meter	1 sariya (12 m)	Sariya per quintal	Sariya per tonne	Sariya per bundle
6 mm	0.222	2.66	37.5	375	12
8 mm	0.395	4.74	21.1	211	10
10 mm	0.617	7.40	13.5	135	7
12 mm	0.888	10.66	9.4	94	5

Weights are IS 1786 nominal values. Rods per bundle is common market practice and can vary by brand. Actual weight can vary by about ±3–7% as allowed by IS 1786.

Sariya Weight Formula

Weight (kg/m) = D × D ÷ 162

D is the sariya diameter in mm. Multiply by 12 for one full sariya.

Example: 12 mm sariya: 12 × 12 ÷ 162 = 0.889 kg/m, so one 12 m sariya weighs about 10.66 kg.

How Many Sariya in 1 Ton?

Divide 1000 by the weight of one sariya. For 12 mm: 1000 ÷ 10.66 = about 94 sariya per tonne. For 8 mm: 1000 ÷ 4.74 = about 211 sariya.

Why Actual Weight Can Differ

Steel is rolled to a size range, not an exact size, so the weight on the weighbridge is rarely exactly the calculated weight.

TMT bars (IS 1786): the mass per meter may vary by about ±7% for bars up to 10 mm, ±5% for 12–16 mm and ±3% for bars above 16 mm.
Plates and sheets (IS 1852 / IS 2062): thickness has a rolling tolerance, so a "10 mm" plate can be slightly thicker or thinner.
Pipes and sections: corner radius, weld seam, zinc coating and end finish (plain or screwed) change the weight a little.

Use the calculated (nominal) weight for estimates and quotations, and the actual weighbridge weight for billing.
