Weights Formulas

So. Dunno about other guys on here but i'm always on the hunt for good info regarding weights.
Some of you might know some might not, info is king and be the difference between a good day scrapping or a waste of time.
I have a notebook i keep of all relevant info to scrapping and looking to add more. Dont have much but willing to share what i have in the hopes that
people would be willing to share what they have. For example



Mass of Steel Plates.

Length x Width x Thickness x 7.85 ( Density per cubic meter of mild steel) = Total weight in kgs.

To work out other materials (Brass, Alloy) same equation but diff density. (can find lists online)





Pipe Mass Calculation

Outside Diameter (OD) - Wall Thickness x Wall Thickness x 0.02466 = kgs /per mtr x Length = Total weight in kgs.


If anyone has anything to help out other scrappers, throw it up and ill keep doing the same as i find it..
