About Metric Ton-Force
One metric tonne-force (tf) is the gravitational force on 1,000 kg under standard gravity - exactly 9,806.65 N = 9.80665 kN. It dominates international heavy engineering: crane hook capacities are rated in tf (a '50-tonne crane' lifts 50 tf = 490.3 kN); ship mooring lines, anchor holding power, and cargo lashing per IMO standards are in tf; hydraulic presses for metal extrusion and stamping in Europe and Asia are rated in tf. ISO 7531 lifting-gear working load limits (WLL) use tf. 1 tf = 1,000 kgf = 9,806.65 N = 2,204.6 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.
