I'm reading too many things giving me nitrate and phosphate concentrations in µmols but I speak ppms.
I'm sure since I learned to read ppm's in the hobby that it's wrong or at least antiquated.
Can someone tell me how to convert ppm's of NO3 and PO4 to µmols?
I have only gathered enough to know that it's not a straightforward conversion factor kind of thing.
Thanks for any answers or pointers!!
P.S. If you can also explain, if both units are usable for expressing concentration, why we measure in ppm instead of µmols, it would hopefully be interesting.
