About Centinewtons
A centinewton (cN) is exactly 0.01 N - the standard force unit of the textile industry. ISO and ASTM specs give fibre tenacity in cN/tex (centinewtons per tex, where 1 tex = 1 g/km): high-tenacity polyester 70-80 cN/tex; Kevlar/Twaron para-aramid 200-250 cN/tex; Dyneema/Spectra UHMWPE >350 cN/tex. Sewing thread breaking strength is 200-800 cN. Packaging tensile testers, adhesive peel-force instruments, and fine spring calibrators all report in cN. 1 cN ≈ 1 pond (0.980665 cN). 100 cN = 1 N.
About Pound-Force
The pound-force (lbf) is the gravitational force on 1 lb-mass under standard gravity - exactly 4.4482216152605 N. It dominates US structural, mechanical, and aerospace engineering: AISC and ACI structural codes use lbf and kips (1 kip = 1,000 lbf); tire pressure 'psi' means lbf/in²; engine torque in lb·ft. Aircraft thrust is quoted in lbf: the GE90-115B (Boeing 777) produces 115,300 lbf = 513 kN. Spring rates, fastener torques, and load cell calibrations across North America are in lbf. 1 lbf = 4.44822 N = 16 ozf = 32.174 pdl.
