About this calculator

Use case

Estimate HSS tube tonnage with dimensions you can audit.

Use width, height, wall thickness, density, quantity, and allowance with formula traceability.

Range notes

Wall thickness must stay below half of the smaller tube side.

Square tube uses the same width and height value.

Quantity and allowance are applied to order weight.

Supports catalog or custom material density with kg/m³ and lb/in³ input.

Inverse mode solves required tube length from a target weight.
