Conversion Formula
kN/m = mN/m × 1.000000000e-6
About Millinewtons per metre
The millinewton per metre (mN/m) equals 10⁻³ N/m, the most widely used practical unit for liquid surface tension worldwide. Water at 20 °C: 72.8 mN/m; ethanol: 22.1 mN/m; mercury: 485 mN/m; olive oil: ~32 mN/m. Numerically identical to dyn/cm, erg/cm² and mJ/m². 1 mN/m = 10⁻³ N/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.
