How it was calculated
The weight is the section area multiplied by the material density:
kg/m = S² × 0.866 × 0.00785, where S is the size across flats in mm.For Hexagon bar SW12, the section area is 1.25 cm², so 1 metre = 1.25 × 0.785 = 0.979 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
