To calculate the weights of Bright Steel Bars in kg/metre, use the following formulae:Hexagons - (size a/f in mm)2 x .006798 = weight per metre in kilograms Squares - (size a/f in mm)2 x .00785 = weight per metre in kilograms 2 x .006165 = weight per metre in kilograms Rounds - (Diameter in mm) Flats - Width in mm x thickness in mm x .00785 = weight per metre in kilograms.
