Calculate the volume first by multiplying the cross sectional area with length.
Multiply the volume with density of mild steel which will give the weight.
The density of Mild steel is 7850 kg/ m3
e.g
Calculate the weight of 2 m rod having cross sectional area of 5 m2
Volume = 2x5 = 10 m3
Weight = 10 x 7850 = 78500 kg
Be specific that same units are used all around the calculations.
For simple geometries like plate the weight = area x thickness x material density
For complex parts = volume x material density

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)
To calculate the weight of a given amount of steel in the metric system you simply multiply the volume of steel in cubic meters times the SG of steel (typically 7.85 but it varies slightly depending on the type of steel). The answer will be in metric tonnes or MT.
as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m. the steel weight is actually calculated, as a % of the cross-sectional area. different applications have different minimum % steel required, roughly work on 1%. the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
Calculate the length of steel you are going to use the building and muliply the length with unit weight of the steel.ex: 12 m 25mm steel weight is12 x 3.85 =46.2 kg3.85 kg/m is the unit weight of 25mm bar
by calculating I=1/12bh3

How do you calculate steel weight without using steel table book?
Ignore the zinc content. Just calculate the volume of steel in the given type (e.g schedule 40), size and length of pipe and multiply by the density of that grade of steel.
how calculate steel in concrete
measure it
If the bar is circular then it is: pi*radius square
by the ton
For surface area of steel bar= pi*diameter*length For cross-sectional area of steel bar= pi (dia)^2/4
