About Newtons per metre
The newton per metre (N/m) is the SI derived unit of surface tension, equal to one joule per square metre. Adopted in all modern scientific publications and engineering codes. Water at 20 °C: 0.0728 N/m; mercury: 0.485 N/m; liquid iron at 1 550 °C: ~1.8 N/m. 1 N/m = 1 J/m² = 1 000 mN/m = 1 000 dyn/cm.
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.
