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 Ø25, the section area is 4.91 cm², so 1 metre = 4.91 × 0.785 = 3.853 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
