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 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.
