About Millinewton per meter (mN/m)
A metric surface-tension unit equal to exactly 0.001 N/m, numerically identical to the CGS dyne/cm. Because typical liquids range 10-80 mN/m, this is the practical working unit in chemistry, formulation science, and surface engineering. Surfactant and detergent formulators use mN/m to characterize CMC (Critical Micelle Concentration) data and emulsion stability per ASTM D1331 and ISO 304; ink, paint, and coating developers use mN/m to spec dispersion stability and substrate wettability; fuel-cell and battery membrane researchers report electrolyte / ionomer surface energies in mN/m; pharmaceutical formulation labs (USP <1059>) measure parenteral and ophthalmic formulation surface tension to predict in-vivo behavior. Reference values: water 72.8 mN/m at 20 °C (the universally memorized calibration baseline), pure ethanol 22.4 mN/m, common surfactant solutions 25-40 mN/m above CMC.
About Dyne per centimeter (dyn/cm)
A CGS surface-tension unit numerically identical to the SI mN/m (1 dyn/cm = 1 mN/m exactly). Dyne/cm is the traditional unit in coatings, printing inks, adhesives, and pharmaceutical chemistry literature, and is preserved in widely-used industrial test methods: ASTM D2578 'Wetting Tension of Polyethylene and Polypropylene Films' (the corona-treatment 'dyne test' where calibrated dyne-pen solutions in 30-60 dyn/cm increments are wiped on plastic film to check post-treatment surface energy before printing — a polyethylene film needs typically ≥38 dyn/cm to print legibly with water-based ink, ≥44 dyn/cm for solvent-based; corona/plasma treatment raises untreated PE from ~31 to 42-46 dyn/cm), ASTM D971 'Interfacial Tension of Insulating Liquids' for transformer-oil quality assessment (fresh oil ≥40 dyn/cm, replacement threshold ~22 dyn/cm), pharmaceutical excipient quality control per USP <1059>, and most pre-1980s US surface-chemistry textbooks (Adamson 'Physical Chemistry of Surfaces', Davies & Rideal 'Interfacial Phenomena', Defay-Prigogine 'Surface Tension and Adsorption'). Remains the de-facto unit in flexographic, gravure, and offset printing process specifications.
