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 Pond

The pond (p), also called gram-force (gf), is the gravitational force on 1 g under standard gravity - exactly 9.80665 × 10⁻³ N. It belongs to the metric gravitational technical system that dominated continental European engineering before SI. One thousand ponds = one kilopond (kp) = kilogram-force (kgf). Laboratory balances reading in grams technically measure pond, not mass. Older Mettler and Sartorius balance specs quote spring forces in pond. Pre-SI textile tensile strength was expressed in pond/tex. 1 p = 1 gf = 9.80665 mN = 0.001 kgf.
