HOW TO CALCULATE WEIGHT OF STEEL BARS IN FEET

HOW TO CALCULATE WEIGHT OF STEEL BARS IN FEET

(D)²/533

Is the formula to calculate the weight of steel bars in KG/ft

So the weight of 10 mm bar will be,

(10 x 10) / 533 = 0.188 kg/ft 

similarly, the weight of bars will be as follows,

.

Unit weight of steel is d square/533. How is it derived?

To be accurate W= D²/533 it is

Its is derived from the very basic concept

I.E., weight = density x volume

it is also can be written as weight = density x (area x length)

since ,

density of steel in meter =7850 kg/m³ > 7850/(1000X1000X1000) kg/mm

Length= 1 m

Area = π(pi) x d²/ 4

Unit Weight of Steel Bar (in Kgs) = (3.14 X D^2)/4 X 1000 X 7850 / (1000 X 1000 X 1000)

Therefore, weight = (7850 x (3.14/4) d² x 1000) / (10⁹)

= d² x 0.00616225 which is also can be written as

=(d²/1) x (0.00616225/1)

= d² / (1/162.2)

=d²/162.2

( 1 metre = 3.28084 feet)

Weight of steel per feet = d2/(162.27 x 3.28084)

= d2/532.38 ≈= d2/533 (say)
