Convert Millinewtons (mN) to Dynes (dyn) instantly and accurately.
Conversion Formula
dyn = mN × 100
About Millinewtons
A millinewton (mN) is 10⁻³ N - the force scale of lightweight structures and precision connectors. A mosquito weighs ~1-3 mN; a grain of rice ~29 mN; a paper clip ~40 mN. USB connector insertion forces are specified at 40-80 mN; keyboard switch actuation (ISO 9241) 40-80 mN. Piezoelectric hard drive head positioning actuators deliver 10-100 mN. Spider dragline silk (4 µm diameter) breaks at 40-60 mN - among the highest specific strengths in nature. Flexible electronics peel-force and thin-film adhesion tests also operate in the mN range. 1 mN = 10⁻³ 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.
