What is steel or metal round bar unit weight calculator?
Steel or metal round bar unit weight calculator, calculates weight per meter length and total length after input of dia in mm, length in meter, and density of metal in Kg/Cum.
In this Soved’s calculator, we can calculate unit weight, unit cross section area, unit volume, total cross section area, total volume, and total weight any metals/non metals like as Copper, Aluminium, Steel, Wood balli, Silver, and Zinc etc with all input data. Here some metals densities are written below-
Steel density- 7850-7860Kg/Cum
Aluminium density- 2640-2830Kg/Cum
Copper density- 8800-8990Kg/Cum
Example-1: Calculate unit weight and total weight of steel round bar with 20mm dia and 50m total length. Take density of steel 7850Kg/Cum.
Solution:
For unit weight,
Steel bar dia,d= 20mm
Steel bar unit length,l= 1m
Steel density,p= 7850Kg/Cum
Steel bar unit weight= steel bar unit volume*steel density
Steel bar unit weight= π*d*d*0.25*0.001*0.001*l*p
Where, π= 3.14159, d= 20, l= 1, p= 7850
Steel bar unit weight= 3.14159*20*20*0.25*0.001*0.001*1*7850
Steel bar unit weight per meter=2.466Kg
For total weight,
Steel bar dia,d= 20mm
Total no of steel bar,n= 1
Steel bar total length,l= 50m
Steel density,p= 7850Kg/Cum
Steel bar total weight= steel bar total volume*steel density
Steel bar total weight= π*d*d*0.25*0.001*0.001*l*p*n
Where, π= 3.14159, d= 20, l= 50, p= 7850, n= 1
Steel bar total weight= 3.14159*20*20*0.25*0.001*0.001*50*7850*1
Steel bar total weight=123.307Kg
For unit cross section area,
Steel bar dia,d= 20mm
Steel bar unit cross section area in mm²= π*d*d*0.25
Where, π= 3.14159, d= 20mm
Steel bar unit cross section area= 3.14159*20*20*0.25
Steel bar unit cross section area=314.159mm²
For total cross section area,
Steel bar dia,d= 20mm
Total no of bar,n= 1
Steel bar total cross section area in m²= π*d*d*0.001*0.001*0.25*n
Where, π= 3.14159, d= 20mm, n= 1
Steel bar total cross section area= 3.14159*20*20*0.001*0.001*0.25*1
Steel bar total cross section area=0.000314m²
For unit volume per meter,
Steel bar dia,d= 20mm
Steel bar length,l= 1m= 1000mm
Steel bar unit volume per meter in mm³= π*d*d*0.25*l
Where, π= 3.14159, d= 20mm, l= 1000mm
Steel bar unit volume per meter in mm³= 3.14159*20*20*0.25*1000
Steel bar unit volume per meter =314159.00mm³
For total volume,
Steel bar dia,d= 20mm
Steel bar length,l= 50m
Number of steel bar,n= 1
Steel bar total volume in m³= π*d*d*0.001*0.001*0.25*l*n
Where, π= 3.14159, d= 20mm, l= 50m, n=1
Steel bar total volume in m³= 3.14159*20*20*0.001*0.001*0.25*50*1
Steel bar total volume=0.016m³
Example-2: Calculate unit weight and total weight of aluminium round bar with 10mm dia and 12m total length. Take density of aluminium 2700Kg/Cum.
Solution:
For unit weight,
Aluminium bar dia,d= 10mm
Aluminium bar unit length,l= 1m
Aluminium density,p= 2700Kg/Cum
Aluminium bar unit weight= aluminium bar unit volume*aluminium density
luminium unit weight= π*d*d*0.25*0.001*0.001*l*p
Where, π= 3.14159, d= 10, l= 1, p= 2700
Aluminium bar unit weight= 3.14159*10*10*0.25*0.001*0.001*1*2700
Aluminium bar unit weight per meter=0.212Kg
For total weight,
Aluminium bar dia,d= 10mm
Aluminium bar total length,l= 12m
Aluminium bar number,n= 1
Aluminium density,p= 2700Kg/Cum
Aluminium bar total weight= aluminium bar total volume*aluminium density
Aluminium total weight= π*d*d*0.25*0.001*0.001*l*p*n
Where, π= 3.14159, d= 10, l= 12, p= 2700, n= 1
Aluminium bar total weight= 3.14159*10*10*0.25*0.001*0.001*12*2700*1
Aluminium bar total weight=2.545Kg
Short formula for steel round bar unit weight.
Suppose dia of bar in mm= d
Unit length of bar in meter= 1
Steel density in Kg/cum= 7850
Steel unit weight in Kg/meter= ?
So, Steel weight= steel volume*steel density
Steel unit weight in Kg/meter= π*d²*0.25*0.001*0.001*1*7850
Steel unit weight in Kg/meter= 3.14159*d²*0.25*0.001*0.001*1*7850
Steel unit weight= d²/162.196 ~ d²/162 Kg/m
Steel unit weight per meter= d²/162 Kg
Where d in mm
