It is not possible to answer this question. A milligram (mg) is a measure of mass while a millilitre is a measure of volume. The two measure different things and it makes no sense to try to convert from one to the other without additinal information. For example, a mg of water would take up approx 13 times the volume of a mg of Mercury. You need to kow the density of the liquid in question.
To convert grams to milligrams, you multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 300 grams is equal to 300,000 milligrams (300 g × 1,000 mg/g = 300,000 mg).
1000 mg equals 1 gram so the answer would be 3000 mg
87.6 mg = 0.0876 grams
255mg is equal to 0.255 grams (mg divided by 1,000 OR mg x 0.001 = grams)** 1 gram = 1000mg
There are 453.59237 grams in one pound. Therefore to get amount of pounds in grams, value in grams has to be divided by amount of grams in one pound: 300 grams = [grams] / 453.59237 = 300 / 453.59237 = 0.6614 pounds
0.526 grams
1 mg = .001 grams, so 2632.4 mg = 2.6324 grams.

2.5grams=2500 mg
9mg = 0.009 grams (mg divided by 1,000 OR mg x 0.001 = grams)* * 1 gram = 1000mg
75 mg = 0,075 grams
1 mg of iron is equal to 0.001 grams of iron.
