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 Dynes per centimetre
The dyne per centimetre (dyn/cm) equals 10⁻³ N/m - the CGS unit of surface tension, numerically identical to mN/m, mJ/m² and erg/cm². Still widely used in older scientific literature and industrial tensiometry: water = 72.8 dyn/cm; surfactant solutions typically 30-60 dyn/cm above the CMC. 1 dyn/cm = 1 mN/m = 1 erg/cm².
