Answer / maninderdeep singh

We know the formula D2/162 which is being used for
calculate unit weight of reinforcement per meter.
Here I am willing to explain how it has been arrived D2/162
(Note: D unit is in MM)
Weight of bar per meter = Area of steel bar X Density of
steel x Length of bar
= (3.14 x D2/4) x 7850 kg/m3 x 1 m
= D2 X 6162.25/(1000x1000)
= D2 X (0.006162)
= D2 X 1/(0.006162)-1
= (D2/162.28)

The actual value is D2/162.28

Kindly note that this function is only applicable for
circular shape steel which density is 7850kg/m3

Answer / azam

this is the co effieent factor after express of 7850 kg/m3.

Answer / santosh singh

density of steel - 7850 kg/m3
weight of steel per meter= 3.142/4 x (d/1000)2 x 7850
solving thiswt / meter of steel rod = d2/162.19

Answer / venkatesh

this is the co effieent factor for steel weight
