Yes, and one part per million is equal to on mg/L
Edit: Please ignore the answerers below that say it has to be all volume or all mass (weight). It is the common way to report contamination in water as parts per million and parts per billion, equivalent to mg/L and ug/L. For instance, the maximum contaminant level for benzene in water as set by the EPA is 5 ug/L or 5 parts per billion.

My Answer:
A part per million = mass of substance / mass of sample * 10^6 = 1 mircogram / mL
A part per thousand = mass of substance / mass of sample * 10^3 = 1 mg / mL
So, a part per thousand is equal to a milligram per millilter.

Yes, if the liquid is water. mg is a measure of mass while ml is a measure of volume, so the two quantities can't be directly compared. However, for water alone 1 ml has a mass of 1 gram, so for water the answer to your question is yes. For another liquid however, such as alcohol, a part per thousand would not be equal to a mg per ml.

No.
1 part per thousand is:
1milliliter per liter (volumetric),
or
1 milligram per gram (mass or weight ratio)

No. It would be a milligram per gram, or a milliliter per liter. Or one milli-anything per 1 unit of anything.
