About Pound per Foot (lb/ft)
An imperial linear-density unit used in US structural engineering, petroleum pipe specifications, and marine chain/rope specs. Structural steel shapes in the US are named by their weight — a "W14×90" is a 14-inch wide-flange weighing 90 lb/ft. Oil-country tubular goods (OCTG) casing and tubing are quoted in lb/ft. 1 lb/ft ≈ 1.488 kg/m.
About Pound per Inch (lb/in)
An imperial linear-density unit used occasionally for small US-made wire, small structural sections, and some legacy specifications. 1 lb/in = 12 lb/ft ≈ 17.86 kg/m. Less common than lb/ft but appears in specialty tooling and small-section references.
