About Newtons per metre
The newton per metre (N/m) is the SI derived unit of surface tension, equal to one joule per square metre. Adopted in all modern scientific publications and engineering codes. Water at 20 °C: 0.0728 N/m; mercury: 0.485 N/m; liquid iron at 1 550 °C: ~1.8 N/m. 1 N/m = 1 J/m² = 1 000 mN/m = 1 000 dyn/cm.
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.
