FAQ

What is the conversion factor from dyn/cm to lbf/ft?
1 dyn/cm equals 6.852177e-5 lbf/ft. To convert, multiply the value in dynes per centimetre by 6.852177e-5.
How do I convert 1 dyn/cm to lbf/ft?
1 dyn/cm = 6.85218e-5 lbf/ft. For any value, multiply by 6.852177e-5.
How do I convert lbf/ft back to dyn/cm?
Divide by the same factor — or equivalently, multiply by 14593.9. So 1 lbf/ft = 14593.9 dyn/cm.
When would I need to convert dyne per centimetre to pound-force per foot (surface tension)?
Surface-tension conversions between dyn/cm and lbf/ft 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).
