About Kilogram-Force
The kilogram-force (kgf), also called the kilopond (kp), is the gravitational force on 1 kg under standard gravity - exactly 9.80665 N. It was the primary force unit in continental European engineering before SI. ISO 1000 (1973) and EU Directive 80/181/EEC deprecated it in favour of the newton. Spring and bathroom scales reading in 'kg' technically measure kgf. Older DIN and JIS materials standards give tensile strength in kgf/mm² (× 9.80665 = MPa). Hydraulic cylinder ratings in legacy European machinery use kgf or tonne-force. 1 kgf = 9.80665 N = 2.20462 lbf.
About Nanonewtons
A nanonewton (nN) is 10⁻⁹ N - the force scale of AFM, MEMS, and nanoscale adhesion. AFM contact-mode tip-sample forces are held to 1-100 nN to image surfaces without damage. A single gecko seta generates ~200 nN of adhesion via van der Waals forces; one million setae per foot give ~10 N total grip. Smartphone MEMS accelerometers sense nanonewton inertial forces from proof-mass displacements. Carbon nanotubes fracture at forces in the nanonanonewton range per tube. CubeSat cold-gas microthrusters produce single-digit nN thrust for attitude control. 1 nN = 10⁻⁹ N.
