About Grams-force per centimetre
The gram-force per centimetre (gf/cm) equals g_n × 10⁻³ / 10⁻² = 0.980665 N/m - a gravitational metric unit that appeared in early tensiometry where ring and plate instruments were calibrated in grams. 1 gf/cm ≈ 0.9807 N/m ≈ 980.7 mN/m, close to but slightly less than 1 N/m. Rarely used after SI adoption. 1 gf/cm = 0.980665 N/m.
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.
