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 Ø8, the section area is 0.50 cm², so 1 metre = 0.50 × 0.785 = 0.395 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
