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 Piconewtons per metre
The piconewton per metre (pN/m) equals 10⁻¹² N/m, used in ultra-sensitive line-tension measurements of surfactant monolayers at the Langmuir trough and in atomic force microscopy (AFM) calibration. Lipid domain boundary line tensions in biological membranes are typically 1-10 pN. 1 pN/m = 10⁻³ nN/m = 10⁻⁹ mN/m.
