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 inch
The pound-force per inch (lbf/in) equals (0.45359237 × 9.80665) / 0.0254 ≈ 175.127 N/m, used in US industrial specifications for adhesive peel strength, hot-melt bond lines, and surface tension of molten metals. 1 lbf/in = 12 lbf/ft ≈ 175.127 N/m ≈ 175 127 mN/m.
