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.
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.
