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 Micronewtons per metre
The micronewton per metre (µN/m) equals 10⁻⁶ N/m, used in precision thin-film capillarity studies and cryogenic surface-tension measurements. Liquid helium-4 at 2 K has a surface tension of ~0.37 mN/m (370 µN/m); liquid ³He near absolute zero is even lower. Numerically identical to µJ/m². 1 µN/m = 10⁻³ mN/m.
