Convert surface tension across 11 units: SI (N/m, mN/m, μN/m, J/m², mJ/m²), CGS (dyn/cm = 1 mN/m, erg/cm², dyn/mm), and Imperial (lbf/ft, lbf/in, pdl/ft). Reference: water 20°C = 72.75 mN/m, mercury = 485, ethanol = 22.1, acetone = 23.7 mN/m. 100% browser-based.

How to Use

  1. 1Type a surface tension value (e.g. 72.75 for water at 20°C in mN/m)
  2. 2Select your starting unit (e.g. mN/m, dyn/cm, N/m)
  3. 3Select your target unit - the result appears instantly
  4. 4All 11 conversions appear across SI, CGS, and Imperial groups
  5. 5Hover any row to copy or use as input; click ⇄ to swap
  6. 6Open 'Liquid surface tension reference' for common liquid values
