Formula for steel bar weight per meter = D2/162 where D is diameter of bar
volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)
l multiply 2.66 multiply (D)squre
=D^((D^2/162) L) D^2 = Diameter of the rod L = Length of the rod
It is a deformed round steel bar and has a diameter of 12mm.

The formula to calculate the area of a steel bar is A = πr^2, where A represents the area and r is the radius of the steel bar. This formula assumes that the steel bar is circular in shape. If the steel bar is a different shape, such as rectangular or square, the formula to calculate the area would be different based on the dimensions of the bar.
If the bar is circular then it is: pi*radius square

Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars. For Eg. - Area of 10mm bar = 78.53 sq.mm Area of 8mm bar = 50.26 sq.mm No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical] In practical u'll provide 2-8mm bars.
Assume area of circle= area of squareπd2/4=L2L=0.88263 x dDeduct the cover from L from both sides. This will be length of bar
Assuming that the bar is made of steel & of circular cross-section & loaded in simple tension, Stress= Load applied/area of the bar. In SI units, area = Pi x (diameter)2/4 "square metre" Apply the load in "Newtons". then calculate the stress developed in N/m2
The number of pieces in one ton of steel bar varies depending on the size and weight of the individual bars. Standard sizes like 20mm or 25mm diameter bars can range from around 65 to 80 pieces per ton.

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
