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.
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
0.526 grams
1 mg = .001 grams, so 2632.4 mg = 2.6324 grams.
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
8
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.
4.37mg is equal to 0.00437 grams (mg divided by 1,000 = grams)** 1 gram = 1,000mg
