Parts per million as CaCO₃ to millimoles per liter
Type a value in ppm to get it in mmol/L instantly.
0.07993mmol/L
Nothing on our list is smaller: soft, poorly buffered water is 2.5× higher. That is low: the pH here can swing sharply overnight.
What it means
How well buffered is it?
Alkalinity is reported as calcium carbonate by convention, even though most of it is really bicarbonate. That convention is what makes the units comparable.
The math
How to convert ppm to mmol/L
To convert parts per million as CaCO₃ to millimoles per liter, multiply by 0.00999132.
Example: 8 ppm × 0.00999132 = 0.0799305 mmol/L.
In the other direction, 1 mmol/L = 100.087 ppm.
