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 Dynes
The dyne (dyn) is the CGS unit of force - the force to accelerate 1 g at 1 cm/s² - exactly 10⁻⁵ N. Surface tension is universally expressed in dyn/cm (= mN/m): water 72.8 dyn/cm; mercury 487 dyn/cm; ethanol 22.1 dyn/cm. Astrophysics and plasma physics papers use dyn/cm² for pressure; solar photon radiation pressure at Earth's orbit is ~4.56 × 10⁻⁵ dyn/cm². The dyne pairs naturally with other CGS units (poise, erg, gauss), which is why it persists in stellar modelling and X-ray binary spectra literature. 1 dyn = 10⁻⁵ N = 10 µN.
