§  Weight of steel in kg/meter = d2/162 (where d is diameter of bar in mm)

§  Weight of steel = density X cross section X Wt. of bar

                              =  7850 X 10 X d2/162     (where dia. in mm)
                                                                         (density of steel is 7850)
