About Piconewtons per metre
The piconewton per metre (pN/m) equals 10⁻¹² N/m, used in ultra-sensitive line-tension measurements of surfactant monolayers at the Langmuir trough and in atomic force microscopy (AFM) calibration. Lipid domain boundary line tensions in biological membranes are typically 1-10 pN. 1 pN/m = 10⁻³ nN/m = 10⁻⁹ 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.
