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 Ergs per square centimetre
The erg per square centimetre (erg/cm²) equals 10⁻³ N/m - the CGS surface energy unit (1 erg/cm² = 10⁻⁷ J / 10⁻⁴ m² = 10⁻³ J/m² = 10⁻³ N/m). Standard in solid surface-energy measurements: polyethylene ~31 erg/cm²; glass ~300-500 erg/cm²; metals 500-2 000 erg/cm². 1 erg/cm² = 1 mN/m = 1 dyn/cm.
