dxd/162 this"s the formula

so 8x8/162=0.4 kg weight per mt

Answer / mohsin uddin jafri

The standard formula for calculating the weight of a steel
rod of any Diameter is {[(D^2)/(162)]*L}.

Where; D is diameter of Rod
L is length of Rod whose weight is to be
calculated.

Ususlly L doesnt come but putting L in formula is very
useful for calculating the weight of total length of a bar.

If in formula L doesnt come than the weight of the rod is
of one meter length.

For Example:

To calculate the weight of 8 mm dia bar of 1 meter length.

={(D^2)/(162)*L}
={(8^2)/(162)*1}
={(64)/(162)*1}
={0.4*1}
=0.4 kg

Similarly calculate the weight of bar of any Diameter.

d \ 162 is ur 1meter weight now multiply

forexmpl 8*8=64\162=.395
now .395 is ur running meter

Answer / c.m.vijaya kumar

dead weight of steel is 7850 kg/cum
formula
(area of bar) x (1 metre of bar) = volume of bar

(3.14/4 x d/1000 xd/1000) x 1 metre = volume of bar

(0.000000785 x d xd)cum (dia convert to metre)
1 cum of steel is 7850 kg

so (0.0000007845 xd xd) cum of steel bar is
(0.000000785 x d x d) x 7850 =0.006162 x d x d
8mm bar 1m wt is 0.006162 x 8 x 8 = 0.394368kg

d*d/162 = in kgs

Answer / neelam

The standard formula for calculating the weight of a steel
rod of any Diameter in Kg/m is [(D^2)/(162.162)].

Where; D is diameter of Rod

To calculate the weight of 8 mm dia bar of 1 meter length.

={(D^2)/(162.162)} x L (Length of bar)
={(8^2)/(162.162)} x 1
={(64)/(162.162)} x 1
={0.395 * 1}
=0.395 kg

Similarly calculate the weight of bar of any Diameter.

Answer / s.mani

d*d\162 and 3.14*r*r*steel density

8*8\162=0.395kg/mt

3.14*4*4*7.86ton/m3 of steel=394.88grams/mt

Answer / david richmond majaw

Dia of a steel bar = 8mm = 0.008m
Density of the steel = 7850 Kg/cum
Length of the steel bar = 1m
Weight of the steel bar = Cross sectional area of steel x
length x density of steel
= (pi x d x d)/4 x L x 7850
{(22/7)x0.008 x 0.008}/4 x 1 x 7850
= 0.3947 Kg
= say 0.40 Kg.
