How it was calculated

The weight is the section area multiplied by the material density:

kg/m = width × thickness × 0.00785, in mm.

For Flat bar 20×3, the section area is 0.60 cm², so 1 metre = 0.60 × 0.785 = 0.471 kg.

The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
