About Joules per square metre
The joule per square metre (J/m²) equals 1 N/m exactly - the surface-fracture-energy (G_c) form used in fracture mechanics and wetting thermodynamics. Values: silica glass ~0.8 J/m²; aluminium ~1.4 J/m²; silicon carbide ~10-25 J/m²; tough metals 50-100 J/m². 1 J/m² = 1 N/m = 1 000 mJ/m².
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.
