Aluminium tube weight calculator
Calculate the weight of round aluminium tube from outer diameter, wall thickness, length and alloy. Common for handrail, piping and structural inserts.

Formula
Weight (kg) = π/4 × (OD² − ID²) × L × ρ
Use consistent units: the calculator works in the dimensions shown. ρ is alloy density in kg/m³.
Example
A 5083 tube 50 mm OD × 3 mm wall × 1,000 mm long weighs about 1.21 kg.
