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.
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.
