Convert Millijoules per square metre to Kilonewtons per metre
Convert Millijoules per square metre (mJ/m²) to Kilonewtons per metre (kN/m) instantly and accurately.
Conversion Formula
kN/m = mJ/m² × 1.000000000e-6
About Millijoules per square metre
The millijoule per square metre (mJ/m²) equals 10⁻³ N/m - the SI surface-energy-per-area form, numerically identical to mN/m and dyn/cm. The preferred notation in materials science for solid surface energy and work of adhesion: polypropylene ~30 mJ/m², epoxy ~45 mJ/m², steel ~2 000 mJ/m². 1 mJ/m² = 1 mN/m = 1 dyn/cm.
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.
