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 Tex (tex)

A textile-industry linear-density unit equal to exactly grams per 1,000 meters of fiber or yarn (= 10⁻⁶ kg/m = 1 mg/m). Tex is the ISO-standard fiber-fineness unit worldwide per ISO 2060 'Yarn from Packages — Determination of Linear Density (Mass per Unit Length)'. Used universally in: tire-cord industry per ASTM D885 (polyester tire cord 1,100-1,650 tex; rayon cord 1,840-2,750 tex; aramid/Kevlar cord 1,580-2,840 tex; steel-wire tire-belt 4,400 tex), industrial belting and conveyor-belt reinforcement fabrics, carpet and rug yarn (Berber loop-pile typical 2,000-5,000 tex; nylon BCF 1,400 tex), sewing-thread and embroidery-thread specifications, polypropylene woven slings for material handling, and continuous-filament-yarn (CFY) manufacturing. Direct measurement principle: weigh 1,000 m of the fiber under standardized 20 °C / 65% RH atmosphere per ISO 139, heavier fiber = higher tex. Convert tex to g/km (numerically identical); to denier by multiplying by 9; to kg/m by dividing by 10⁶.

Understanding Pounds per Foot

The Pound per Foot (symbol: lb/ft) is a unit of linear density. 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).

Convert lb/ft to kg/m by multiplying by 1.4882; to lb/in by dividing by 12.

It belongs to the imperial measurement system.

Pounds per Foot are commonly used in textile manufacturing, cable engineering, and structural analysis.

Understanding Tex

The Tex (symbol: tex) is a unit of linear density. A textile-industry linear-density unit equal to exactly grams per 1,000 meters of fiber or yarn (= 10⁻⁶ kg/m = 1 mg/m). Tex is the ISO-standard fiber-fineness unit worldwide per ISO 2060 'Yarn from Packages — Determination of Linear Density (Mass per Unit Length)'. Used universally in: tire-cord industry per ASTM D885 (polyester tire cord 1,100-1,650 tex; rayon cord 1,840-2,750 tex; aramid/Kevlar cord 1,580-2,840 tex; steel-wire tire-belt 4,400 tex), industrial belting and conveyor-belt reinforcement fabrics, carpet and rug yarn (Berber loop-pile typical 2,000-5,000 tex; nylon BCF 1,400 tex), sewing-thread and embroidery-thread specifications, polypropylene woven slings for material handling, and continuous-filament-yarn (CFY) manufacturing. Direct measurement principle: weigh 1,000 m of the fiber under standardized 20 °C / 65% RH atmosphere per ISO 139, heavier fiber = higher tex. Convert tex to g/km (numerically identical); to denier by multiplying by 9; to kg/m by dividing by 10⁶.

Tex are commonly used in textile manufacturing, cable engineering, and structural analysis.
