Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

mcg is an unofficial abbreviation for microgram. The proper symbol is µg, where µ is the greek letter mu. Since most people can't type that directly, they either use u or mc to indicate micro.

The prefix micro indicate a value of 1/1,000,000. Hence one µg is 0.000,001 grams.

As you've typed your question in all caps, its difficult to tell if you are asking how to convert µg to mg (milligrams) or Mg (Megagrams). I'm going to assume milligrams, megagrams is not a very well used unit.

To convert µg to mg, first understand the units: micro is 1/1,000,000 and milli is 1/1,000. So there are 0.001 milligrams in a microgram.

If you have 300 µg, that would mean you have:

300 µg x 0.001 mg/µg = 0.3 mg

If you have 3,000 µg:

3,000 x 0.001 mg/µg = 3 mg.
