Generally the tubing shall be designated by its actual outside diameter (O.D) and wall thickness (W.T). The lists presented below provide the weights of tubing in U.S customary units: O.D – inch, W.T – inch, Weight – pound per foot length (lb/ft). They can be converted into ISO metric unit by using the formulas: 1 inch = 25.4 mm, 1 lb = 0.4536 kg, 1 ft = 0.3048 m, 1 lb/ft = 1.4882 kg/m. These tubing weights are applicable to materials of carbon and low alloy steels, and stainless steels.
