How it was calculated
The weight is the section area multiplied by the material density:
kg/m = d² × 0.006165 (0.00617 rounded), where d is the nominal diameter in mm.For Rebar Ø40, the section area is 12.57 cm², so 1 metre = 12.57 × 0.785 = 9.865 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
