About Pounds-force per inch
The pound-force per inch (lbf/in) equals (0.45359237 × 9.80665) / 0.0254 ≈ 175.127 N/m, used in US industrial specifications for adhesive peel strength, hot-melt bond lines, and surface tension of molten metals. 1 lbf/in = 12 lbf/ft ≈ 175.127 N/m ≈ 175 127 mN/m.
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.
