No. Even if that were milliliters to liters, it would still be parts per thousand.
Well, honey, to convert micrograms per kilogram to parts per million, you need to multiply by 1,000. Why? Because there are 1,000 micrograms in a milligram, and 1,000,000 parts per million in a kilogram. So, it's just a matter of shifting those decimal places around to get the job done.
If you have 1 million parts of something 10 parts would be 10 parts per million. If you had 2 million parts of something 20 parts would be 10 parts per million.
You are comparing units of mass with units of volume. You must first decide whether you want parts per million (volume), or parts per million (mass). Then you must either convert the volume to mass, or the mass to volume. For this purpose, you have to know the density of the involved substances.You are comparing units of mass with units of volume.
