Calculate Stainless Steel pipe Weight

Formula For Calculating Stainless Steel Pipe Weight :
201 Stainless Steel round pipe weight
430 Stainless Steel round pipe weight
Weight=(OD-T) * T * 0.02491*length   [OD=mm T=mm length=Meter, weight=KG ]
Such as 304  50.8*1.5mm, 6meters, weight=(50.8-1.5)*1.5*0.02491*6=11.05KG.
