About Newtons
The newton (N) is the SI unit of force - the force to accelerate 1 kg at 1 m/s², defined as 1 N = 1 kg·m/s². Named after Sir Isaac Newton and adopted in 1960. One newton is the weight of a ~102 g apple. Everyday forces: gentle finger press ~1 N; handshake 150-200 N; human bite 500-700 N; car emergency braking 5,000-15,000 N; turbofan engine thrust ~300 kN; Boeing 747 lift at cruise ~2,800 kN. The newton is universally used in science and engineering worldwide. 1 N = 1 kg·m/s² = 0.22481 lbf.
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.
