1000 mcg = 1 mg.
So a 600 mg pill has the active ingrediant of 600 1000mcg pills.
That is the math. But do not substitute pills for each other without consulting a doctor or pharmacist. That could be very dangerous and even cost you your life. For example. the coating on a pill, particularly a time-release pill, could make a huge difference in how a pill works if you try to split it or if you try to take several smaller pills instead of one large pill.
I say 2.5 because 1 milligram = 1000 mcg and if you think about it 400 mcg (1 pill) +400 mcg (1 pill) = 800 mcg + 200 mcg (1/2 pill)= 1000 mcg
I say 2.5 because 1 milligram = 1000 mcg and if you think about it 400 mcg (1 pill) +400 mcg (1 pill) = 800 mcg + 200 mcg (1/2 pill)= 1000 mcg

1000 mcg = 1 mg Thus 1 mcg = 0.001 mg
1 mg = 1000 mcg so 0.5 mg = 0.5*1000 = 500 mcg
An mcg is a microgram, or 10^(-6) of a gram. An mg is a milligram, 10^(-3) grams. Thus 1 mg is equal to 10^3, 1000 mcg.
1 milligram = 1000 micrograms. You now have all the information required to answer the question.
1000 mcg=1mg
1000 mcg = 1 mg so 5000 mcg = 5000/1000 = 5 mg. Simple!
1000 mcg = 1 mg so 215 mcg = 215/1000 = 0.215 mg. Simple!
1000 mcg = 1 mg so 10000 mcg = 10000/1000 = 10 mg. Simple!
There are 1000 mcg in a mg. In addition there are 1000 mg in one gram.
