Convert Joules per square metre to Dynes per centimetre
Convert Joules per square metre (J/m²) to Dynes per centimetre (dyn/cm) instantly and accurately.
Conversion Formula
dyn/cm = J/m² × 1000
About Joules per square metre
The joule per square metre (J/m²) equals 1 N/m exactly - the surface-fracture-energy (G_c) form used in fracture mechanics and wetting thermodynamics. Values: silica glass ~0.8 J/m²; aluminium ~1.4 J/m²; silicon carbide ~10-25 J/m²; tough metals 50-100 J/m². 1 J/m² = 1 N/m = 1 000 mJ/m².
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.
