Glad you asked...
In order to convert a number from MCG to MG all you have to do is move the decimal point three places to the left. For example, 1000 MCG would be 1 MG.
Then again, this answer might help you...
One milligram is equal to 1000 micrograms. To convert micrograms to milligrams, all you need to do is divide the number of micrograms by 1000. Therefore, 8500 micrograms is equal to 8.5 milligrams.
