FAQ

What is the conversion factor from mJ/m² to dyn/cm?
1 mJ/m² equals 1 dyn/cm. To convert, multiply the value in millijoules per square metre by 1.
How do I convert 1 mJ/m² to dyn/cm?
1 mJ/m² = 1 dyn/cm. For any value, multiply by 1.
How do I convert dyn/cm back to mJ/m²?
Divide by the same factor — or equivalently, multiply by 1. So 1 dyn/cm = 1 mJ/m².
When would I need to convert millijoule per square metre to dyne per centimetre?
Surface-tension conversions between mJ/m² and dyn/cm appear in coatings and wettability work, surfactant and interfacial-tension measurement, foam and emulsion characterisation, and capillary/droplet-engineering datasheets. mN/m, dyn/cm and mJ/m² are exact numerical equivalents — they appear interchangeably across SI, CGS and surface-free-energy notations. lbf/ft and lbf/in are common in US petroleum interfacial-tension datasheets and US coatings documentation. This category does not include temperature-dependent material lookups or capillary/contact-angle calculators.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
