8 mm- 0.395 kg per rmt
10mm---0.617 kg per rmt

etc

Answer / murali

To find the unit weight of reinforced for the given diameter.

wt/m = area of bar*unit weight of steel
=22/7*1/4*(D)^2*(7850)/10^6 = 0.0061678*(D)^2
= (1/0.0061678)*D^2 = D^2/162.13

Ex.for 12mm dia.= 12^2/162.13 = 144/162.13= 0.888 kgs/m

Answer / lokesh

all steel running meter to per kg
6mm steel----0.22 running meter per kg
8mm steel----o.39 running meter per kg
10mm steel---0.62 running meter per kg
12mm steel---0.89 running meter per kg
16mmsteel----1.58 running meter per kg

Answer / md gulam moinuddin

As our friend mr ketan khatri had given the correct

explanation for finding the wt/m of any dia (but slight
correction i need to add to that ie, insteed of 164 it is
162) hence using formulae

wt /m (of any dia)=(suare of diametre of that dia)/162

That dia indicates ,the dia for which u need to find the
wt/m

Answer / oretan omowunmi olatunde

16mm diameter bar


weigh factor for 16mm
16 x16 x 0.00617=1.579kg

whatever u get multipy by the weigh factor gives u the
kilogram of the reinforcement

Answer / suresh

7850 kg / cum this is the steel wt. or steel will cal.with
d*d/162

Answer / prabhash mishra

I am totally agree answer posted by Md Gulam Moinuddin, it
should be D*D/162

Answer / nagori salim

weight/metre (kg/m) = d*d/162



Now,
weight (kg) = length * (d*d/162)
= metre * (kg/m)
= kg


where, d = dia of bar.

Answer / nikunj faldu

I am totally agree answer posted by Murali, it
should be D*D/162 right but that's coming from below
calculation. so,this concept is main.

wt/m = area of bar*unit weight of steel
=22/7*1/4*(D)^2*(7850)/10^6 = 0.0061678*(D)^2
= (1/0.0061678)*D^2 = D^2/162.13

Ex.for 12mm dia.= 12^2/162.13 = 144/162.13= 0.888 kgs/m

Answer / adnan kaleemi

d*d/162

d=diameter of a bar in mm

is equal to wt in kg per running meter
