Rebar / Steel Bar Weight Calculator
Steel IS 1786:2008~1 min
Calculate the weight of reinforcement steel bars (TMT/HYSD) for any diameter and length.
Formula
Weight (kg) = D² / 162 × Length
Input Parameters
6, 8, 10, 12, 16, 20, 25, 32, 40 mm
Results
Unit Weight
1.580kg/m
Total Weight
1,580.25kg
Total Weight
1.5802MT
Step-by-Step Method
- 1Unit weight of steel bar = D² / 162 kg/m (where D is diameter in mm).
- 2Total weight = Unit weight × Length per bar × Number of bars.
Engineering Notes
- •Formula D²/162 is derived from density of steel (7850 kg/m³) and π/4.
- •Standard bar lengths: 12 m per piece.
- •Add 3–5% wastage for cutting and bending.
