Conversion Formula
mN/m = dyn/cm × 1
About Dynes per centimetre
The dyne per centimetre (dyn/cm) equals 10⁻³ N/m - the CGS unit of surface tension, numerically identical to mN/m, mJ/m² and erg/cm². Still widely used in older scientific literature and industrial tensiometry: water = 72.8 dyn/cm; surfactant solutions typically 30-60 dyn/cm above the CMC. 1 dyn/cm = 1 mN/m = 1 erg/cm².
About Millinewtons per metre
The millinewton per metre (mN/m) equals 10⁻³ N/m, the most widely used practical unit for liquid surface tension worldwide. Water at 20 °C: 72.8 mN/m; ethanol: 22.1 mN/m; mercury: 485 mN/m; olive oil: ~32 mN/m. Numerically identical to dyn/cm, erg/cm² and mJ/m². 1 mN/m = 10⁻³ N/m.
