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 Joules per square metre
The joule per square metre (J/m²) equals 1 N/m exactly - the surface-fracture-energy (G_c) form used in fracture mechanics and wetting thermodynamics. Values: silica glass ~0.8 J/m²; aluminium ~1.4 J/m²; silicon carbide ~10-25 J/m²; tough metals 50-100 J/m². 1 J/m² = 1 N/m = 1 000 mJ/m².
