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 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.
