Milligrams per liter to micromoles per liter
Type a value in mg/L to get it in µmol/L instantly.
250µmol/L
That's about the same as a healthy river. That is healthy, well-oxygenated water.
Convert the other way: µmol/L to mg/L
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 µmol/L
To convert milligrams per liter to micromoles per liter, multiply by 31.25.
Example: 8 mg/L × 31.25 = 250 µmol/L.
In the other direction, 1 µmol/L = 0.032 mg/L.
The table below is for water at 0 °C, saturation 14.6 mg/L.
