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 Poundals per inch

The poundal per inch (pdl/in) equals 0.45359237 × 12 N/m = 5.44310844 N/m exactly (since 0.3048/0.0254 = 12). A foot-pound-second (FPS) unit rarely encountered in modern practice but found in historical US engineering tables predating SI adoption. 1 pdl/in = 5.44310844 N/m ≈ 5 443 mN/m.
