About Nanonewtons per metre
The nanonewton per metre (nN/m) equals 10⁻⁹ N/m, encountered in AFM force spectroscopy for interfacial line-tension measurements and wetting studies on nanostructured surfaces. Colloidal particle contact lines at fluid interfaces can exert forces in the nN/m range. 1 nN/m = 10⁻³ µN/m = 10⁻⁶ mN/m.
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.
