3. Formula for Calculating S. S. Square Bar Weight :  
    DIA (mm) X DIA (mm) X 0.00788 = Wt. Per Mtr.
DIA (mm) X DIA (mm) X 0.0024 = Wt. Per Feet
4. Formula for Calculating S. S. Hexagonal Bar Weight:
    DIA (mm) X DIA (mm) X 0.00680 = Wt. Per Mtr. 
DIA (mm) X DIA (mm) X 0.002072 = Wt. Per Feet
5. Formula for Calculating S.S. Flat Bar Weight:  
    Width (mm) X Thick (mm) X 0.00798 = Wt. Per Mtr. 
Width (mm) X Thick (mm) X 0.00243 = Wt. Per Feet
 
       
6. Formula for Calculating S.S. Sheet & Plates Weight:
    Length (mtrs) X Width (mtrs) X Thick (mm) X 8.068 = Wt. Per PC. 
Length (feet) X Width (feet) X Thick (mm) X 3/4 = Wt. Per PC
7. Formula for Calculating S.S. Circle Weight:
    Dia (mm) X Dia (mm) X Thick (mm) ÷ 160 = Gms. Per PC 
Dia (mm) X Dia (mm) X Thick (mm) X 0.0000063 = Wt. Per PC
 
8. Formula for Calculating Brass Pipe/ Copper Pipe Weight:  
    O. D. (mm) - Thick (mm) X Thick (mm) X 0.0260 = Wt. Per Mtr.
9. Formula for Calculating Lead Pipe Weight:
   

O. D. (mm) - Thick (mm) X Thick (mm) X 0.0345 = Wt. Per Mtr.

10. Formula for Calculating Aluminium Pipe Weight:  
    O. D. (mm) - Thick (mm) X Thick (mm) X 0.008 = Wt. Per Mtr.  
11. Formula for Calculating Aluminium Sheet Weight:  
    Length (Mtr.) X Width (Mtr.) X Thick (mm) 2.69 = Wt. Per PC  
12. Conversion of Mtrs to Feet:  
    Weight of 1 Mtrs ÷  3.2808  = Weight Per Feet  
13. Bar Low's Formula for Calculating Bursting Pressure:  
    P = 2ST/D or t-DP/25S or S-DP/2t or D = 2st /P
P = Bursting Pressure Psi.  
S = Tensile Strength of Tube  
T = Wall Thickness (in inches)  
D = Outside Diameter (in inches)
