1
The D²/162 Formula
To find the weight of 1 meter of steel, engineers use the formula: (Diameter in mm × Diameter in mm) / 162.28. E.g., a 10mm bar is (100 / 162.28) = 0.617 kg per meter.

Standard Lengths
In India, TMT rebars are manufactured and sold in standard lengths of 12 Meters (approximately 39.5 feet). Some wastage (lapping and cutting) is inevitable.

Buying in Bundles
Steel is sold by weight (Kg/Ton), not by rods. However, knowing the exact weight of a standard rod prevents you from being cheated by underweight, poor-quality steel at the yard.
