To calculate the mass of mild steel plate & flat:
Length X Width X thickness X 7850kg
For Example:
- For a 10mm plate @ 2400mm x 1700mm
- 2.4 x 1.7 x 0.01 x 7850 = 320.28kg
- For a 200 x 6 flat bar @ 1200mm
- 1.2 x 0.2 x 0.006 x 7850 = 11.304kg
Note:
- Most price books have an extra 2.5% added onto the weight of merchant bar as a rolling tolerance.
- Add 2kg per square metre for floorplate.
To calculate the mass of aluminium:
Length x width x thickness x 2710kg
To calculate the mass of stainless steel:
Length x width x thickness x 8000kg
To calculate the mass of black round pipe & tube per metre:
Outside Diameter – wall thickness X wall thickness X 0.0246615
For Example:
- For a 219.1mm diameter x 6.4mm wall thickness line pipe
- 219.1 – 6.4 x 6.4 x 0.0246615 = 33.57kg/meter
- For 25nb med blk pipe
- 33.7 – 3.2 x 3.2 x 0.0246615 = 2.4kg/metre
Note:
- Most price books have an extra 2.5% added onto the weight of pipe as rolling tolerance.
To calculate the mass of round bar per metre:
Diameter squared x 0.7854 x 7850 kg
For Example:
- For 50mm round bar
- 0.05 x 0.05 x 0.7854 x 7850 = 15.41kg/meter
To calculate the circumstance of a circle:
Diameter x 3.1416
For Example:
- For a diameter of 350mm
- 350 x 3.1416 = 1099.56mm
To calculate the diagonal length corner to corner in a square or rectangle: (Hypotenuse)
Length squared + breadth squared - then square root
For Example:
- For a rectangle 1200mm x 2400mm
- (1200 x 1200 = 1440000) + (2400 x 2400 = 5760000) = 7 200 000
- 7200000 > square root = 2683.28mm
