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 Ø159×8, the section area is 37.95 cm², so 1 metre = 37.95 × 0.785 = 29.791 kg.

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