About Piconewtons
A piconewton (pN) is 10⁻¹² N - the force scale of molecular biology and nanotechnology. Optical and magnetic tweezers apply 0.1-100 pN forces to single DNA strands and protein complexes. Unzipping one DNA base pair requires ~10-15 pN; a kinesin motor protein stalls at ~7 pN. AFM cantilevers resolve piconewton van der Waals forces between single atoms and surfaces. The covalent C-C bond ruptures under ~4,000 pN in controlled AFM pulling experiments. These forces underpin mechanobiology, drug-target mechanics, and nanofabrication. 1 pN = 10⁻¹² N.
About Ounce-Force
One ounce-force (ozf) is 1/16 of a pound-force - approximately 0.2780 N. It is used for small-scale US customary force measurements: postal scales, miniature connector insertion forces, and small latch springs. Hobby servo motor torque is rated in oz·in (ounce-inches); dividing by arm length gives force in ozf. Snap, zipper, and hook-and-loop closure test gauges specify pull-off forces in ozf. Cosmetic packaging component actuation forces (lipstick, compact closures) also use ozf. 1 ozf = 1/16 lbf = 28.3495 gf = 0.27801 N.
