Formula

Formula
mN/m = dyn/cm × 1

Multiply any value in dynes per centimetre by 1 to obtain the value in millinewtons per metre.

Worked example

Convert 72 dyn/cm to mN/m.

  1. 01Start with 72 dyn/cm.
  2. 02Multiply by the conversion factor: 72 × 1 = 72 mN/m.
Result72 dyn/cm = 72 mN/m

FAQ

What is the conversion factor from dyn/cm to mN/m?
1 dyn/cm equals 1 mN/m. To convert, multiply the value in dynes per centimetre by 1.
How do I convert 1 dyn/cm to mN/m?
1 dyn/cm = 1 mN/m. For any value, multiply by 1.
How do I convert mN/m back to dyn/cm?
Divide by the same factor — or equivalently, multiply by 1. So 1 mN/m = 1 dyn/cm.
When would I need to convert dyne per centimetre to millinewton per metre?
Surface-tension conversions between dyn/cm and mN/m 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).
