About Ounce-Force
One ounce-force (ozf) is 1/16 of a pound-force - approximately 0.2780 N. It is used for small-scale US customary force measurements: postal scales, miniature connector insertion forces, and small latch springs. Hobby servo motor torque is rated in oz·in (ounce-inches); dividing by arm length gives force in ozf. Snap, zipper, and hook-and-loop closure test gauges specify pull-off forces in ozf. Cosmetic packaging component actuation forces (lipstick, compact closures) also use ozf. 1 ozf = 1/16 lbf = 28.3495 gf = 0.27801 N.
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.
