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 Ø21.3×2, the section area is 1.21 cm², so 1 metre = 1.21 × 0.785 = 0.952 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
