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.

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.
