Convert Poundals per inch to Dynes per centimetre
Convert Poundals per inch (pdl/in) to Dynes per centimetre (dyn/cm) instantly and accurately.
Conversion Formula
dyn/cm = pdl/in × 5443.10844
About Poundals per inch
The poundal per inch (pdl/in) equals 0.45359237 × 12 N/m = 5.44310844 N/m exactly (since 0.3048/0.0254 = 12). A foot-pound-second (FPS) unit rarely encountered in modern practice but found in historical US engineering tables predating SI adoption. 1 pdl/in = 5.44310844 N/m ≈ 5 443 mN/m.
About Dynes per centimetre
The dyne per centimetre (dyn/cm) equals 10⁻³ N/m - the CGS unit of surface tension, numerically identical to mN/m, mJ/m² and erg/cm². Still widely used in older scientific literature and industrial tensiometry: water = 72.8 dyn/cm; surfactant solutions typically 30-60 dyn/cm above the CMC. 1 dyn/cm = 1 mN/m = 1 erg/cm².
