According to my reference the following are what is correct:

milligram - mg - 1/1000 grm
microgram - µg - 1/1,000,000 gram
kilogram - kg - 1,000 gram
Megagram - Mg - 1,000,000 gram
centagram - cg - 100 gram

Thus

Mcg is Mega Centa gram, which would be 10,000 grams or 10 kilogram,
which is 10,000,000,000 time larger than a µg..
