Steel Weight Calculator – MS Bar Rod Flat Angle Weight
Calculate MS steel weight per metre for round bars, square bars, flat bars, hex bars and angle sections. Uses standard density of 7850 kg/m³.
Steel Weight Formulas
Round Bar: Weight (kg/m) = D² × 0.00617
Square Bar: Weight (kg/m) = A² × 0.00785
Flat Bar: Weight (kg/m) = W × T × 0.00785
20mm round bar, 6m, 10 pieces:
kg/m = 20² × 0.00617 = 2.468 kg/m
Total = 2.468 × 6 × 10 = 148.08 kg

Frequently Asked Questions
The standard density of mild steel (MS) is 7850 kg/m³. This is used in all structural steel weight calculations internationally.
Weight = D² × 0.00617 = 12 × 12 × 0.00617 = 0.888 kg per metre. For a 6m bar: 0.888 × 6 = 5.33 kg.
