FAQ

What is the conversion factor from lbf/in to gf/cm?
1 lbf/in equals 178.5797 gf/cm. To convert, multiply the value in pounds-force per inch (surface tension) by 178.5797.
How do I convert 1 lbf/in to gf/cm?
1 lbf/in = 178.58 gf/cm. For any value, multiply by 178.5797.
How do I convert gf/cm back to lbf/in?
Divide by the same factor — or equivalently, multiply by 0.005599741. So 1 gf/cm = 0.00559974 lbf/in.
When would I need to convert pound-force per inch (surface tension) to gram-force per centimetre?
Surface-tension conversions between lbf/in and gf/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).
