Common Surface Tension Conversions
- 1 N/m = 1 000 mN/m = 1 000 dyn/cm = 1 J/m²
- 1 mN/m = 1 dyn/cm = 1 erg/cm² = 1 mJ/m² (four units, numerically identical)
- Water at 20 °C: 72.8 mN/m = 72.8 dyn/cm = 0.0728 N/m
- Mercury at 20 °C: 485 mN/m = 485 dyn/cm = 0.485 N/m
- 1 J/m² = 1 N/m = 1 000 mJ/m² (surface energy = surface tension)
- 1 lbf/ft ≈ 14.594 N/m ≈ 14 594 mN/m
- 1 lbf/in ≈ 175.127 N/m ≈ 175 127 mN/m
- 1 kN/m = 1 000 N/m = 106 mN/m
