formula calculation of steel round bar
>
Area (square metres) of cross section * 7850 = kilograms per metre length.
For other lengths, multiply answer by length in metres.
Theoretical weight of steel, a unit of measurement is kilograms (kg). The basic formula is:
W (weight, kg) = F (basal area mm2) × L (length, m) × ρ (density, g/cm3) × 1 / 1000
Steel density: 7.85g/cm3
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
kg = 6.16546 x width mm x OD2 x bore2 ---- 1000000
=3.14 x d2 /4 x 7850x1m =3.14x(8)2/4 x7850 =50.24x 7850 =394384x1m =394383/(1000x1000) =0.394 =0.394kg/m
volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)
To calculate the weight of a given amount of steel in the metric system you simply multiply the volume of steel in cubic meters times the SG of steel (typically 7.85 but it varies slightly depending on the type of steel). The answer will be in metric tonnes or MT.

How do you calculate steel weight without using steel table book?
measure it
by the ton
ferrite calculate formula?
kg = 6.16546 x width mm x OD2 x bore2 ---- 1000000
by using calculator
depends on the steel.
d*2*pie/4*l*0.785 Were d is Daimeter of the job, Pie value is 3.142, l is Lenght of the job.
DxD/162 this is the formula for finding unit weight of steel
density=mass/volume 7.850=2500kg/(0.47*L*0.914) Ravindra
