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.
About Attonewtons
An attonewton (aN) is 10⁻¹⁸ N - the force scale of individual photon recoil and quantum vacuum effects. The thermal noise floor of an AFM cantilever at room temperature is ~1-10 aN/√Hz. A 532 nm photon absorbed by a trapped ion imparts ~0.3 aN of recoil. Casimir forces between conducting surfaces 10-100 nm apart are 1-100 aN. NEMS resonators have demonstrated force sensitivity below 1 aN/√Hz, enabling single-molecule adsorption detection. Optomechanical cavities probe radiation pressure at the attonewton scale to test quantum measurement limits. 1 aN = 10⁻¹⁸ N.
