I see people writing mcg for the amount of Thyroxine, etc. they are taking.
Are people mistaking micrograms (mcg) for milligrams (mg)?
I got the following from the Internet -
One milligram is one thousandth of a gram and one thousand micrograms. A milligram is generally abbreviated as mg. One microgram is one millionth of a gram and one thousandth of a milligram. It is usually abbreviated as mcg or ug.
I take a porcine thyroid tablet daily - 162.5mgs (or milligrams), which is 162500mcgs. The equivalent of 2.5077582 grains - a measurement used for raw thyroid.
I hope this is helpful
