87.23mmHg
That's about the same as a healthy river. That is healthy, well-oxygenated water.
What it means
How much oxygen is in there?
Saturation values are for fresh water at sea level. Seawater holds about 20% less, and altitude lowers it further.
The math
How to convert mg/L to mmHg
Saturation depends steeply on temperature: % = mg/L ÷ saturation × 100, where saturation is 14.6 mg/L at 0 °C and 7.6 at 30 °C. The figures below use the temperature selected above.
Example: 8 mg/L = 87.2329 mmHg.
The table below is for water at 0 °C, saturation 14.6 mg/L.
