About Pound per Foot (lb/ft)
An imperial linear-density unit (≈ 1.4882 kg/m per NIST SP 811). The single most important imperial linear-density unit in US engineering because US structural-steel shapes are NAMED by their lb/ft mass per AISC convention: 'W14×90' designates a 14-inch nominal-depth wide-flange beam weighing exactly 90 lb/ft (the second number is always the lb/ft mass). The AISC Steel Construction Manual lists every rolled-steel shape — W, S, M, HP, HSS, C, MC, L, WT, MT — by its lb/ft nominal weight. Also the universal unit for oil-country tubular goods (OCTG) casing and tubing per API 5CT (a typical 5-1/2 inch OD production tubing is 17 lb/ft; 9-5/8 inch OD intermediate casing is 47 lb/ft), petroleum pipeline specifications per API 5L (a 30-inch OD crude-oil pipeline at 0.5-inch wall is ~158 lb/ft), and marine anchor-chain ratings per ABS / DNV (3-inch stud-link anchor chain ~90 lb/ft). Convert lb/ft to kg/m by multiplying by 1.4882; to lb/in by dividing by 12.
About Denier (den)
A textile-industry linear-density unit equal to exactly grams per 9,000 meters of fiber or yarn (≈ 1.111 × 10⁻⁷ kg/m = 0.1111 tex). The 9,000-meter basis is preserved from the historic Lyon, France silk-trade measurement standard. Denier ('den' or simply 'D') is the everyday consumer-textile fineness unit: pantyhose and nylon-stocking weight ratings (10-15 den ultra-sheer; 20-40 den medium; 40-80 den opaque; 100-200 den support hosiery), fishing-line braided ratings (Sufix 832, PowerPro, Daiwa J-Braid product lines list denier alongside lb-test), parachute-cord and military 550-cord nylon ripstop fabric per MIL-DTL-32439 (210D - 1680D ranges), outdoor-gear rip-stop nylon and Cordura fabric specifications (Cordura 1000D is the rugged standard for backpacks and tactical equipment; 500D and 330D are lighter weights; Cordura HP and TrueLock have engineered variants), and silk-fabric weight ratings (4.5-8 momme silk shirting; 35+ momme heavyweight silk). 1 denier ≈ 0.111 tex ≈ 1.111 × 10⁻⁷ kg/m.
