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.
About Pound per Inch (lb/in)
An imperial linear-density unit equal to exactly 12 × lb/ft (≈ 17.858 kg/m per NIST SP 811). lb/in is used occasionally in US engineering for small-cross-section components where lb/ft would produce small decimal values: small US-manufactured precision-machined wire (round bar stock from McMaster-Carr / MSC Industrial Supply lists weight-per-inch for small diameters), specialty tooling (broaches, taps, drills, gun-barrel stock), small structural sections in MIL-SPEC aerospace and defense applications (MIL-STD-1539 microelectronics-package mass-spec sheets, occasional small-airframe spar-cap weight-per-inch in legacy aircraft drawings), and some pre-1980s machine-shop reference tables. 1 lb/in = 12 lb/ft ≈ 17.86 kg/m. Much less common than lb/ft in everyday US structural engineering but persists in specialty tooling, fastener-stock, and small-arms ammunition projectile-weight specifications.
