Convert Poundals per inch to Kilonewtons per metre
Convert Poundals per inch (pdl/in) to Kilonewtons per metre (kN/m) instantly and accurately.
Conversion Formula
kN/m = pdl/in × 0.00544310844
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 Kilonewtons per metre
The kilonewton per metre (kN/m) equals 1 000 N/m = 10⁶ mN/m - applied in geotechnical engineering for electro-osmotic soil surface-tension effects and in materials science for metal-ceramic interfacial fracture energy. Alumina-aluminium interfaces: ~0.5-1 kN/m; diamond-metal bonds: several kN/m. 1 kN/m = 1 000 N/m = 10⁶ mN/m.
