Convert Pounds-force per inch to Kilonewtons per metre
Convert Pounds-force per inch (lbf/in) to Kilonewtons per metre (kN/m) instantly and accurately.
Conversion Formula
kN/m = lbf/in × 0.1751268352
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 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.
