nN = mgf × 9806.65

About Milligram-Force

One milligram-force (mgf) is the gravitational force on 1 mg under standard gravity - exactly 9.80665 × 10⁻⁶ N. It is the natural unit for ultra-precise analytical balances: a 0.001 mg readability balance resolves ~9.8 nN = 0.001 mgf. MEMS force sensors in precision weighing cells are specified in mgf. Watchmaking uses mgf gauges to measure hairspring and detent actuation forces. Entomology and microbiology measure insect and microorganism attachment forces in mgf. Aerospace composite strain sensors are calibrated with mgf reference weights. 1 mgf = 9.80665 µN = 0.980665 dyn.

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.
