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/cm³

Screw Thread Steel Weight Calculation Formula

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 Weight Calculation Formula

(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 Weight Calculation Formula

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 Weight Calculation Formula

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

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

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

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 Weight Calculation Formula

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
