The rectangular tube weight calculator is the go-to tool for structural engineers, fabricators, and contractors who work with Rectangular Hollow Sections (RHS). Whether you need a rectangular tube weight calculator in kg, a rectangular tube weight calculator metric, the rectangular hollow section weight per meter, an RHS weight calculator, an aluminium rectangular tube weight calculator, a tubular steel weight calculator, a steel weight calculator in kg, or the steel tubing weight per foot calculator — this single free tool covers every combination. Enter your tube dimensions, select your material, and get instant accurate weight results.
| Size (A×B mm) | 2mm | 2.5mm | 3mm | 4mm | 5mm |
|---|
Choose your tube material (MS, Stainless, Aluminium etc.) and unit system — metric (mm) or imperial (inches). The calculator auto-converts imperial inputs to metric for calculation.
Enter the outer dimensions of the rectangular tube. A is the wider face, B is the narrower face. For example, a 100×50mm RHS has A=100 and B=50. Both measured outside-to-outside.
Enter the uniform wall thickness in mm or inches. Standard RHS sections typically range from 1.6mm to 12mm thickness depending on the size. Check your section specification sheet.
See weight per meter (kg/m), total weight in kg and lbs, weight per foot in lbs, cross-sectional area, and number of pieces per tonne — all essential for procurement and logistics planning.
Where: A = Width (mm) | B = Height (mm) | T = Wall Thickness (mm) | Density = g/cm³
Alternative formula: Weight/m = (A×B − (A−2T)×(B−2T)) × Density ÷ 1000
Example: 100×50mm, 3mm wall, MS: Area = (100×50) − (94×44) = 5000−4136 = 864 mm²
Weight/m = 864 × 7.85 ÷ 1000 = 6.78 kg/m
Weight per foot: kg/m × 0.3048 × 2.20462 = lbs/ft
Switch between mm and inches — the calculator auto-converts and gives results in kg/m, lbs/m, and lbs/ft simultaneously. Perfect for projects with mixed unit specifications from Indian and international clients.
Automatically calculates how many pieces fit in one tonne — extremely useful for procurement orders, transport planning, and cost estimation on construction projects with bulk material requirements.
Complete rectangular hollow section weight per meter chart for common sizes (50×25 to 200×100mm) across standard wall thicknesses — no need to calculate for every standard size manually.
From rectangular tube weight in kg metric to steel tubing weight per foot, from MS to aluminium rectangular tube weight — this free RHS weight calculator handles every combination. With a built-in weight chart, pieces-per-tonne output, and both metric and imperial support, it's the most complete rectangular hollow section weight tool available online. Bookmark it for every fabrication and construction project.
