You have them wrong way round, a gram is heavier than a milligram!
A milligram is a unit of mass equal to one thousandth (10-3) of a gram - so there are
1000 milligrams in a gram.
milli means thousandths
so 21 grams is 21 thousand milligrams
21 000 mg
4 900 000 milligrams in 4900 grams (1000 milligram per gram).
1,000 milligrams (mg) per gram.
There are 0.001 grams in a milligram.
The number of millimoles in a milligram depend on the molecular weight of the substance in question. The molecular weight tells how many grams per mole a substance has, and thus how many millimoles in a milligram.
0.5 grams, I think.
1/1000 grams
.001 grams = 1 milligrams
0.001 grams = 1 milligram
0.002
0.0001 of them.
one thousand
1/1000 grams in 1 milligram
