About Kilonewtons
A kilonewton (kN) is 1,000 N - the standard force unit for structural engineering outside North America. A 70 kg person exerts ~0.687 kN; a heavy goods vehicle axle 100-130 kN; a loaded Boeing 747 on its landing gear ~2,800 kN. Eurocode and BS EN structural codes express beam loads and foundation reactions in kN and bending moments in kN·m. Universal testing machines for materials testing are rated 10-10,000 kN. Prestressed concrete tendons are stressed to 100-250 kN each. 1 kN = 1,000 N = 224.81 lbf = 101.97 kgf.
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.
