Milligrams is a metric measure of mass. Gallons is an English measure of liquid volume. While you could do the conversion you would first need to know what liquid you were converting. Milk, gasoline, water they all have different mass per gallon. A milligram is a very small amount of any of these. 1 milligram = 1/1000th of a gram.
There can be no equivalence.
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 water. How many milligrams?
The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
Many people believe that there is an exact conversion between a milligram and a millilitre (and therefore litre and so gallon) for pure water. But that is not true and has not been true since 1964 when the definition of the litre was changed.

How many milligrams of isopropyl alcohol in a gallon?
First, you need to know the density of the isopropyl alcohol, which is about 0.785 g/cm^3. Next, you need to know how many cm^3 are in a gallon. 1 gallon = 231 in^3 = 231 * (2.54)^3 cm^3 = 3785 cm^3 Also, we need to convert from grams to milligrams 1 gram = 1000 milligrams so... (.785 g/cm^3) * (1000 milligrams/gram) * (3785 cm^3/gallon) * (1 gallon) = 2,970,000 mg

How many milligrams equal a gallon?
Milligrams, a unit of mass, and gallons, a unit of volume, are not actually directly equivalent, however it is common to use the volume and mass of water to "equate" the two. Using that method, where 1 (U.S.) Gallon of water weighs 128 ounces, and 1 ounce weighs 28.35 grams (approx.) or 28,350 mg 1 Gallon "equals" 128 * 28,350 mg, or 3,628,739 mg
