Steel Weight Calculation

 

There so many types of steel in the world. Such as the screw thread steel, steel tube, steel round bar, square steel and etc. So it is necessary to calculate its weight in the work time. The information of the steel weight calculation formula can help you get over it.

First of all, I need to show something for you guys about the unit of measurement.

1M=3.281"
1"=25.4MM
1 Pound=0.4536 Kilogram
1 Kilogram Force=9.81 N
1 MPa=145.161 Pound/Inch
The density of steel: 7.8g/cm³
The density of stainless steel: 7.78g/cm³
The density of aluminum: 27g/cm

Steel weight calculation formulas

  • Screw Thread Steel

Screw Thread Steel

Diameter(mm)*Diameter(mm)*0.00617*Length(m)
If the diameter is 20mm and length is 12m
You can get that: 20*20*0.00617*12=29.616kg

  • Steel Tube

Steel Tube

(outside diameter - wall thickness) * wall thickness(mm)*0.02466*Length(m)
If the outside diameter is 20mm, wall thickness is 5mm and the length is 5m
You can get that:
(20-5)*5*0.02466*5=9.2475kg

  • Steel Round Bar

steel round bar

Diameter(mm)*Diameter(mm)*0.00617*Length(m)
If the diameter is 20mm and the length is 10m
You can get that:
20*20*0.00617*10=24.68kg

  • Square Steel

square steel

Width(mm)*height(mm)*length*0.00785
If the width and height are 40mm, the length is 6m
You can get that:
40*40*6*0.00785=75.36kg

  • Flat Steel

flat steel

Width(mm)*height(mm)*length*0.00785
If the width is 50mm, height is 40mm, the length is 5m
You can get that:
50*40*5*0.00785=78.5kg

  • Hexagonal Steel

Hexagonal Steel

Inside diameter*inside diameter*length(m)*0.0068
If the inside diameter is 40mm and the length is 5m
You can get that:
40*40*5*0.0068=54.4kg

  • Steel Plate

steel plate

7.85*length(m)*width(m)*thickness(m)
If the length is 6m, width is 2m and the thickness is 2m
You can get that:
7.85*6*2*2=188.4kg

  • Equal Leg Angle

Equal Leg Angle

Width*thickness*0.015*length(m)
If the size of the side edge is 60mm, the thickness is 6mm and the length of it is 5m
You can get that:
60*6*0.015*5=27kg
