From Wikipedia, the free encyclopedia   (Redirected from Μg)
Jump to: navigation, search  In the metric system, a microgram
(µg; or sometimes: mcg) is a unit of mass equal to one millionth
(1/1,000,000 or 1×10−6) of a gram, or one thousandth (1/1000 or
1×10−3) of a milligram. The unit symbol is µg according to the
International System of Units. In µg the prefix symbol for
micro- is the Greek letter µ.  The United States-based Joint
Commission recommends that hospitals do not use the symbol µg in
handwritten orders due to the risk that the prefix µ (micro-)
might be misread as the prefix m (milli-), resulting in a
thousandfold overdose. The non-SI symbol mcg is recommended
instead.[1]  Gamma (symbol: γ) is a non-SI unit of mass equal to
one microgram. This always-rare use is currently deprecated.
