FAQ

What is the conversion factor from gf/cm to lbf/ft?
1 gf/cm equals 0.0671969 lbf/ft. To convert, multiply the value in grams-force per centimetre by 0.0671969.
How do I convert 1 gf/cm to lbf/ft?
1 gf/cm = 0.0671969 lbf/ft. For any value, multiply by 0.0671969.
How do I convert lbf/ft back to gf/cm?
Divide by the same factor — or equivalently, multiply by 14.88164. So 1 lbf/ft = 14.8816 gf/cm.
When would I need to convert gram-force per centimetre to pound-force per foot (surface tension)?
Surface-tension conversions between gf/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).
