in steel bar weight formula (d^2/162).so what is 162.

Answer Posted / ankit panchal

Weight of bar = d^2/162 x lenghth of barfor 1000 mm (1 meter) length Reinforcement rod
Weight = Volume X Density
Weight = (Area x Length) X Density
Weight = ( Pi/4 x d^2 x Length) X Density
= (3.14/4 x d^2 x 1000) X 7850
Density of steel is in Kg/m^3 & Length is in MM
So Lets Convert Density of steel KG/m^3 to MM (7850 / 1000x1000x1000 (i.e. m^3) )
= (0.785 x d^2x1000) X 0.00000785
= d^2 x 0.00616225
Lets assume 1
= d^2/1 x 0.00616225/1
Let reverse
= d^2 / 1 / 0.00616225
= d^2 / 162.278
Say d^2 / 162
