About Pounds-force per inch

The pound-force per inch (lbf/in) equals (0.45359237 × 9.80665) / 0.0254 ≈ 175.127 N/m, used in US industrial specifications for adhesive peel strength, hot-melt bond lines, and surface tension of molten metals. 1 lbf/in = 12 lbf/ft ≈ 175.127 N/m ≈ 175 127 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.
