Conversion Formula
mJ/m² = dyn/cm × 1
About Dynes per centimetre
The dyne per centimetre (dyn/cm) equals 10⁻³ N/m - the CGS unit of surface tension, numerically identical to mN/m, mJ/m² and erg/cm². Still widely used in older scientific literature and industrial tensiometry: water = 72.8 dyn/cm; surfactant solutions typically 30-60 dyn/cm above the CMC. 1 dyn/cm = 1 mN/m = 1 erg/cm².
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.
