Engineering CalculationSteel Weight Calculator - Bars, Plates, Pipes, Angles and Sections
Find the weight of reinforcement bars, plates, pipes and rolled sections for estimates, purchase and site checks.
Open the calculator →Formula
Round bar (kg/m) = D² / 162 (D in mm, steel density 7850 kg/m³)
Plate (kg) = length (m) × width (m) × thickness (mm) × 7.85
Worked example
16 mm TMT bar, 12 m long
Weight = 16² / 162 = 1.580 kg/m → 12 m bar = 18.96 kg
Plate 2 m × 1 m × 10 mm = 157.0 kg
Where engineers use it
