HOW TO FIND OUT THE QUANTITY OF STEEL FE415
Question Submitted By :: Civil-Engineering
I also faced this Question!! Answer Posted By
sq of dia divided by 162
then unit will in kg/meter Vijendra Singh
Sq.of the dia of the bar by 162 x length of the bar then
unit will in kgs
it should be
Dia of the bar is in mm
Length of the bar is in m then only Quantity of steel in kgs Sandy
QUANTITY OF STEEL :3.14 / 4 * d2 * 7850
(sq. of d)
EG. IF DIA OF STEEL ROD IS 12mm = 12/1000 = 0.012metre
QUANTITY OF STEEL PER METRE RUNNING STEEL ROD IS
= 3.1416/4 X [0.012]2 X 7850 = 0.89 KG/METER
OR IT CAN BE FOUND BY ....
QTY OF STEEL = d2/162.19 kg per running meter
where d is dia of bar

0.00618 x square of the dia of bar in mm x length of the
bar in mtr.= quantity in kg/mtr. B. K. Iragar
According to IS Code the weight for Fe 415 or 250 or 500,
Unit wt of steel*area of reinforcement=Wt of rod(1m) Kiran Babu T
consider it for 1m length,
unit wt. of steelxarea of reinforcement=quantity
unit wt. of steel = 78.5 kg/cm2
area of reinforecement = (22/7/4)dsquare T Kiran Babu
1. Unit wt of steel Ws = 0.785 kg/cm^2/meter length.
2. Crossectional Area (As) of steel can be found using
As = pi x d^2/4
where d = dia of rebar in cm.
3. Now, wt of steel = Ws x As kg/m
d = 16 mm
Wt of steel per meter lenght = 0.785 x 3.1428 x (1.6)^2/4
= 1.58 kg/ meter length of bar
This can be simplified for calculation as below:
Wt of steel = square of dia in mm/162 (kg/ meter length)
Note:- This is very simple method where we must remember to
mention dia in millimeter to get result in kg per
meter length of rebar.

pls check my ans.
if 12mm bar - .62*1.2*1.2 - .89 kg/m
if 16mm bar - .62*1.6*1.6 - 1.59 kg/m
if wrong pls inform Jayaraaj
Dia of bar square/162= wt kg/m.
