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 Kilogram per Meter (kg/m)
The SI unit of linear density (mass per unit length) per ISO 80000-4. kg/m is the universal working unit for: structural-steel unit weights per Eurocode 3 + ArcelorMittal / British Steel / Tata Steel section catalogs (an IPE 200 wide-flange is 22.4 kg/m, IPE 400 66.3 kg/m, HEB 300 117 kg/m), heavy electrical and telecom cables (a 1,000 kcmil ACSR overhead transmission conductor is ~1.5 kg/m, a 230 kV underground HV cable 30-50 kg/m, fiber-optic submarine cable 6-12 kg/m armored), pipe weight per kg/m specifications per EN 10220 / API 5L / ASTM A53 (a 100 mm Schedule-40 steel pipe is 16.1 kg/m, 200 mm Sch-40 49.3 kg/m, 500 mm Sch-40 200+ kg/m), and rope / chain / wire-rope ratings per ISO 2408 (a 6×36 IWRC 32 mm diameter steel-wire-rope is 4.4 kg/m). Used in structural-engineering dead-load calculations, transportation cargo-loading, crane-and-rigging WLL determination, and material-takeoff estimating.
