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.
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.
