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 Long Ton-Force
One long ton-force is the gravitational force on an imperial long ton (2,240 lb = 20 × 112 lb hundredweight) - approximately 9,964 N. The long ton was the traditional British ton; long ton-force appears in Royal Navy vessel displacement records, British Admiralty anchor chain standards, pre-metrication UK bridge live load codes, and Australian/South African mining bolt pull-out specifications. It sits between short ton-force (8,896 N) and metric tonne-force (9,807 N) - about 12% heavier than a short ton-force. 1 long tf = 2,240 lbf = 9,964.02 N.
