altitude  masl 
saturation % 
For use: Change the numbers and click on question mark.

A click on oxygen calculates oxygen.
Click on saturation calculates saturation.
Click on altitude shows the pressure conversion factor as oxygen (~atm).
(source: pressure of air: Schmassmann, oxygen: Weiss, CRC-Handbook)
precision: O2: 0 ... 25°C ±0.02 mg/l,  >25°: <±0.3 mg/l; temperature range: 0° ... 70°
Remark: Altitude makes sense for oxygen saturation in lakes, because the contact time at surface is unknown. For streams barometer readings should be used.
