How it was calculated

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

kg/m = d² × 0.006165, where d is the diameter in mm.

For Round bar Ø90, the section area is 63.62 cm², so 1 metre = 63.62 × 0.785 = 49.940 kg.

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