About Piconewtons per metre
The piconewton per metre (pN/m) equals 10⁻¹² N/m, used in ultra-sensitive line-tension measurements of surfactant monolayers at the Langmuir trough and in atomic force microscopy (AFM) calibration. Lipid domain boundary line tensions in biological membranes are typically 1-10 pN. 1 pN/m = 10⁻³ nN/m = 10⁻⁹ mN/m.
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.
