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 Microjoules per square metre
The microjoule per square metre (µJ/m²) equals 10⁻⁶ N/m - the surface-energy-per-area form, numerically identical to µN/m since [J/m²] = [N/m] exactly. Used in surface physics for low-energy interface characterisation and in thermodynamic modelling of cryogenic films. 1 µJ/m² = 1 µN/m = 10⁻³ mJ/m².
