Weight (kg) = cross-section area (mm²) × length (mm) × density (kg/m³) ÷ 1,000,000,000. For example, a 25 mm round mild-steel bar that is 1 m long weighs about 3.85 kg. Bhaar Calc does this for you for 25+ shapes.
Mild steel is about 7,850 kg/m³, stainless steel 304 about 7,900 kg/m³, aluminium 6061 about 2,700 kg/m³, copper about 8,940 kg/m³, and common plastics range from about 905 kg/m³ (polypropylene) to 2,200 kg/m³ (PTFE).
Yes. Choose from ABS, acrylic (PMMA), polycarbonate, nylon, acetal (POM), HDPE, LDPE, PP, PVC, PTFE, PET, PETG, PLA, PEEK, PVDF, polystyrene, UHMW-PE and GFRP/FR4 laminate, or enter a custom density.
It is a theoretical weight based on nominal dimensions and typical density. Real products vary with mill tolerances, corner radii, coatings and alloy chemistry, so allow a small margin when ordering or shipping.
Yes. Switch between Metric (mm, kg) and Imperial (in, lb) at the top of the calculator. Your values convert automatically.
Bhaar (भार) means weight in Hindi. Bhaar Calc is a free weight calculator from IRIS Technologies.
