How it was calculated

The weight is the section area multiplied by the material density:

kg/m = (D − t) × t × 0.02466, where D is the outside diameter and t the wall thickness, in mm.

For Round tube Ø88.9×3.6, the section area is 9.65 cm², so 1 metre = 9.65 × 0.785 = 7.573 kg.

The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
