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 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.
