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 Pounds-force per foot
The pound-force per foot (lbf/ft) equals (0.45359237 × 9.80665) / 0.3048 ≈ 14.5939 N/m, used in US reservoir engineering and geotechnical drainage for capillary pressure and interfacial tension data. Drilling muds and reservoir simulation codes (Eclipse, CMG) sometimes report in lbf/ft. 1 lbf/ft ≈ 14.594 N/m ≈ 14 594 mN/m.
