There is no equivalence.
A gram is a measure of mass. A millilitre 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 millilitre of air. How many grams? Next consider a millilitre of lead. How many grams?
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.
Some people still believe that there is a conversion in relation to pure water but that is only approximately true. Until 1964 (nearly 50 year ago!) a litre was defined as the volume of one kilogram of pure water at 4 degrees Celsius and at a pressure of 760 millimetres of Mercury. With that definition a conversion would have been valid - but only for pure water and only under those conditions. In any case that definition of a litre was abandoned in favour of 1 litre =1000 cubic centimetres.
In fact the maximum density of pure water at a pressure of 1 atmosphere (760 ml of mercury) is attained at 4 deg C and is 0.999 972 0 g/ml. At room temperature it is 0.998 2071 g/ml.
Multiply by 1000
There are 1,000 milligrams in a gram.
-- The only way to convert 325 mg to 1 gram is to find another 675 mg somewhere to add to it. 1,000 mg = 1 gram 325 mg = 0.325 gram
To convert from microgram to gram, divide by a million.
A gram is used to measure weight and a km to measure distance. As they measure different things, there is no formula to convert between them.

Multiply by 1000
There are 1,000 milligrams in a gram.
Oh, what a happy little question! To find out how many 250ml are in 18L, we need to convert the liters to milliliters. Since 1L is equal to 1000ml, 18L is equal to 18,000ml. Then we just divide 18,000ml by 250ml to find there are 72 of those little 250ml containers in 18L. Isn't that just delightful?
To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 2 liters is equal to 2000 milliliters. To find out how many 250ml are in 2000ml, you divide 2000 by 250, which equals 8. So, there are 8 250ml in 2 liters.

You don't. A gram is a measure of weight, a gallon is a measure of volume.

A gram is used to measure weight and a km to measure distance. As they measure different things, there is no formula to convert between them.
Multiply by 1000 as there are 1000g in every kg
theres 1000 milligrams in a gram and 1 gram = 0.03527 ounces
A gram is 1/1000 of a litre, so if water, it is equal to a millilitre.
