pound per foot

Linear mass densityexact by definition

The pound per foot is 1.48816... kg/m, following exactly from the exact pound and foot although the decimal does not terminate. It is how North American structural steel is designated: a W12×26 is a 12 inch nominal depth wide-flange section weighing 26 pounds per foot.

Watch out: Pipe weight in lb/ft is for the pipe alone, empty. A water-filled 6 inch schedule 40 steel pipe weighs about 19 lb/ft of steel plus about 13 lb/ft of water, and hanger spacing must be sized for the filled weight plus any insulation.
