About Kilogram-force (kgf)
A legacy metric unit of force equal to the gravitational pull on a 1-kilogram mass at the standard acceleration of gravity g₀ = 9.80665 m/s² (CIPM Resolution 2, 1901), giving exactly 9.80665 N per kgf. Although officially deprecated in favor of the newton under ISO 80000-4 and BIPM SI Brochure §5.4.1, kgf persists in identifiable contexts: tire-pressure gauges in some European countries (a tire pressure of "2.2 kgf/cm²" appears on Russian and Eastern-European specs), industrial-press tonnage ratings expressed in tonnes-force (where 1 tf = 1,000 kgf = 9.80665 kN), cable-tension and lifting-equipment markings in Japanese and older Soviet/Russian engineering drawings, legacy ASME pressure-vessel international-equivalence tables, and motorcycle/bicycle gear-train torque ratings in older European literature. Converting kgf to newtons is multiply by exactly 9.80665; to lbf is multiply by 2.2046.
About Kilonewton (kN)
A metric unit of force equal to exactly 1,000 newtons. The kilonewton is the working unit for structural-engineering loads worldwide except in the United States: beam reactions and column loads in Eurocode 1-7 (EN 1991), cable tensions in cable-stayed bridges and pre-stressed concrete, crane working-load-limit (WLL) markings, bolted-connection capacities (M16 Grade 10.9 has a ~106 kN tensile capacity per EN 1993-1-8), elevator suspension rope safety factors, and the impact loads in EN 1992 / Eurocode 2 reinforced-concrete design. Most ISO and DIN structural standards quote permissible loads in kN. Reference values: a small passenger car weighs ~15 kN, a fully-laden semi-trailer truck 350-400 kN, a typical Class C cargo crane WLL 50-200 kN, a Boeing 777 maximum takeoff weight ~3,500 kN. Convert kN to kips by dividing by 4.448; to tonnes-force by dividing by 9.807.
