About Millijoules per square metre
The millijoule per square metre (mJ/m²) equals 10⁻³ N/m - the SI surface-energy-per-area form, numerically identical to mN/m and dyn/cm. The preferred notation in materials science for solid surface energy and work of adhesion: polypropylene ~30 mJ/m², epoxy ~45 mJ/m², steel ~2 000 mJ/m². 1 mJ/m² = 1 mN/m = 1 dyn/cm.
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.
