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 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.
