Its (D*D)/162 = Unit wt of Tor steel/meter length.
This formula is controversial for huge project ie: estimated Steel usage upto 20k tons.

There we have to go to basics ie: volume x unit wt.

eg: 10mm Tor bar = [3.14 x (D*D)/4] x 1 x 7850 = 0.616225 kg/m
where D= dia in meter
OR

eg: 10mm Tor bar = (D*D)/162 = 0.6178 kg/m
where D= dia in mm

from above examples you can see there is slight diff between two wts.

thus for the project of large quantum, basic formulae should be followed.
