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 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.
