About Microjoules per square metre
The microjoule per square metre (µJ/m²) equals 10⁻⁶ N/m - the surface-energy-per-area form, numerically identical to µN/m since [J/m²] = [N/m] exactly. Used in surface physics for low-energy interface characterisation and in thermodynamic modelling of cryogenic films. 1 µJ/m² = 1 µN/m = 10⁻³ mJ/m².
About Kilonewtons per metre
The kilonewton per metre (kN/m) equals 1 000 N/m = 10⁶ mN/m - applied in geotechnical engineering for electro-osmotic soil surface-tension effects and in materials science for metal-ceramic interfacial fracture energy. Alumina-aluminium interfaces: ~0.5-1 kN/m; diamond-metal bonds: several kN/m. 1 kN/m = 1 000 N/m = 10⁶ mN/m.
