to calculate the weight of diffrent dia bars is d2/162 D=dia of bar , and multiply into 2 times then divide it by 162
Unit Weights of TOR steel bars8mm dia : 0.395 kg/m10mm dia : 0.617 kg/m12mm dia : 0.888 kg/m16mm dia : 1.579 kg/m20mm dia : 2.467 kg/m25mm dia : 3.855 kg/mThese are standard unit weights in India based on the density of steel @ 7850 kg/m3
2.9876 kg/m is the weight of steel bar of 22 mm dia..and you use formula for other bars as d*d/162 Where d is a diameter of bar in mm.
The unit weight of steel is 7850kg per cubic meter, so the unit weight of different bars can be calculated by multiplying the volume of 1m length of bar with the unit weight of steel.It can also be calculated simply by dividing the square of the diameter of bar in mm by 162.Diameter of bar unit weight calculation.8 0.395kg/m w=8x8/16210 0.617kg/m w=10x10/16212 0.889kg/m w=12x12/16216 1.580kg/m w=16x16/16220 2.469kg/m w=20x20/16225 3.858kg/m w=25x25/162
=3.14 x d2 /4 x 7850x1m =3.14x(8)2/4 x7850 =50.24x 7850 =394384x1m =394383/(1000x1000) =0.394 =0.394kg/m

Use the formula for a cylinder to find out the volume. Then multiply the volume by the density of steel (about 7900 kg/m3 - but it may vary slightly depending on the type of steel).
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%
