I am not sure I am following you.

You have a drug with a concentration of 1 mg/ml, and you want to know what that is in ng?

1 milligram (mg) is 1,000,000 nanogram (ng).

1 milliliter (ml) is the same as a cubic centimeter (cc)

If the dose is 4 ng per kg of weight and your pet weighs 87 kilograme, he needs 87*4=348 ng of the drug.

348 nanogram = 0.000348 milligram

Is any of that the information you needed? I was not sure exactly what you were after.
