About Pounds-force per foot
The pound-force per foot (lbf/ft) equals (0.45359237 × 9.80665) / 0.3048 ≈ 14.5939 N/m, used in US reservoir engineering and geotechnical drainage for capillary pressure and interfacial tension data. Drilling muds and reservoir simulation codes (Eclipse, CMG) sometimes report in lbf/ft. 1 lbf/ft ≈ 14.594 N/m ≈ 14 594 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.
