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.
About Pounds-force per foot
The pound-force per foot (lbf/ft) equals (0.45359237 × 9.80665) / 0.3048 ≈ 14.5939 N/m, used in US reservoir engineering and geotechnical drainage for capillary pressure and interfacial tension data. Drilling muds and reservoir simulation codes (Eclipse, CMG) sometimes report in lbf/ft. 1 lbf/ft ≈ 14.594 N/m ≈ 14 594 mN/m.
