How it was calculated
The weight is the section area multiplied by the material density:
kg/m = a² × 0.00785, where a is the side in mm.For Square bar 40×40, the section area is 16.00 cm², so 1 metre = 16.00 × 0.785 = 12.560 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
