Assuming mg is milligrams (the standard abbreviation) the answer is none.

A milligram is a measure of mass. A gallon is a measure of volume. The two measure different things and,according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a gallon of air. How many milligrams? Next consider a gallon of molten lead. How many milligrams?
