How many milligrams equall 1 gallon?

Answer 1

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.

Answer 2

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.

Answer 3

Well, sweetie, a gallon is a unit of volume, not weight. So, it's like asking how many apples are in a football field. It just doesn't make sense. So, to convert gallons to milligrams, you'd need to know the density of the substance you're working with.

Answer 4

Oh, dude, you're hitting me with the tough questions. So, like, there are about 3.785 billion milligrams in a gallon. But, like, who's really counting, am I right? Just pour yourself a glass of water and enjoy life, man.

Answer 5

1gal pure water=8.34lbs

1lb=16oz

1oz=28.3g

1g=1000mg

8.34x16x28.3x1000=math
