Convert Poundals per inch to Pounds-force per foot
Convert Poundals per inch (pdl/in) to Pounds-force per foot (lbf/ft) instantly and accurately.
Conversion Formula
lbf/ft = pdl/in × 0.3729714021
About Poundals per inch
The poundal per inch (pdl/in) equals 0.45359237 × 12 N/m = 5.44310844 N/m exactly (since 0.3048/0.0254 = 12). A foot-pound-second (FPS) unit rarely encountered in modern practice but found in historical US engineering tables predating SI adoption. 1 pdl/in = 5.44310844 N/m ≈ 5 443 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.
