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 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.
