The formula for calculating weight of a solid shaft is dia x dia x length x 7.8 x 1000000. This formula is the most commonly used.
Area in sq. millimetre divided by 127 is the wt. of steel in Kilo Gram (Kg.) per metre length. e.g. 40mm wide flat with thickness 5mm = 40x5 =200/127 = 1.57 kg. 12mm Round bar will have are of 113.14 sq. mm divided by 127 the wt. will be by 0.89 kg. per. mt. length. by H.K. Dua
Density of steel is taken as 7850 kg/cum. Hence unit weight of 50mm dia steel rope will be approximately 15.42 kg/m.

8mm dia : 0.395 kg/m 10mm dia : 0.617 kg/m 12mm dia : 0.888 kg/m 16mm dia : 1.579 kg/m 20mm dia : 2.467 kg/m 25mm dia : 3.855 kg/m These are standard unit weights based on the density of steel @ 7850 kg/m3
0.62 kg/m is the unit weight of 10 mm dia, and you use the thumb rule for all other dia unit weight per metre = d*d/162 where- d is dia of bar/rod in mm
You forgot one important fact.... what material is it made of !

Rolling Margin is the deviation of actual unit weight to that of Standard unit weight as per IS Standards. Rolling Margin is calculated as : Sectional weight = Weight of Steel Bars dia wise / length of the bars. As per IS Standards unit weight of the Bars is calculated as dia x dia / 162 Rolling Margin is deviation of actual sectional weight to that of IS Standard unit weight. Standard Rolling Margin for different dia reinforcement bars used for construction purposes: 8mm to 10mm +- 7% 12mm to 16mm +- 5% 20mm & Above +- 3%

Weight of pipe per Meter in Kg for MS Pipes = 3.14 * (Outer diameter of pipe in Mtr. - wall thickness in Mtr. ) * Wall Thickness in Mtr. * 7850
A standard HSS drill bit in 12mm is all that's needed.
