Conversion of PPM and mg/L
Conversion of PPM and mg/L

I know there was some discussion of this topic once before in relation to TCE, but how do you convert ppm to mg/L if the relative density is not similar to water.
What I have is some reports talking about mg/L of glyphosate in streams and others talking about the potential effects of the chemical at .5 ppm.
I haven't thought about converting things into moles in about 10 years and whenever I try to put it on paper I start to get all jumbled.
This is what I have:
Relative Density of Glyphosate 1.7 (water = 1.0)
if a study quotes 7.55 mg/L what is that in ppm?
Thanks,
Ned

;) it is too easy, you must be convert yours mg/L a ppm using the density of your component. the ppm is for definition mg/kg, then your should be use the next expressions:
[center][b]mg/kg=ppm= mg/L / Density[/b][/center]
but the density is in units of kg/lt, in this case the density is 1.7 kg/L

OK, so let me know if I didn't do this right.
ppm = 7.55 mg/L / 1.7 kg/L
or ppm = 4.44 mg/kg
Is that all! Piece of Cake :D
Gracias al Ingenio!
