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 Kip
One kip (kilo-pound) is exactly 1,000 lbf - approximately 4,448 N. It is the primary force unit in US structural engineering: AISC and ACI 318 specify column loads, beam reactions, and connection capacities in kips and kip·ft or kip·in. 'ksi' (kips per square inch) gives steel yield strength - ASTM A36 yields at 36 ksi; A992/A572 at 50 ksi. Crane capacities, prestressed concrete jacking forces, and soil bearing limits in US geotechnical practice are all in kips. 1 kip = 1,000 lbf = 4,448.22 N = 453.59 kgf.
