How exactly are ppm and μg/ml converted? Seeking advice

How exactly are ppm and μg/ml converted? I’d appreciate some advice. I think it’s not possible to use direct equivalence; instead, it’s necessary to convert m to grams based on the specific gravity l, or to convert μg to volume, in order to be able to relate it to ppm, since ppm is a ratio
This cannot be converted directly; PPM is a ratio of volume to mass, whereas ug/ml generally refers to the ratio of solid mass to volume, and it is mainly used for substances in two different phases
The second floor is correct; the denominator requires a density conversion
