Convert Concentrations or Partial Pressure of
O2, H2, N2O, H2S, or CO2

With the Unisense Unit Converter, you can convert concentrations of gases (μmol/L, %, ppm (vol/vol), ppm (mg/L)) and partial pressure (mm Hg, mBar) of five gases dissolved in water: Oxygen, hydrogen, nitrous oxide, hydrogen sulfide, and carbon dioxide.

You can adjust temperature, salinity, and pressure in relation to your application.

The calculations are based on the articles mentioned below.
