In the scientific and engineering world, the Greek symbol "mu" written as the symbol "µ" is a prefix for micro (one millionth or 10^-6). This is internationally accepted notation.
However, the U.S. FDA does not recognize "µg" to mean micrograms. The FDA insists that "mcg" be used to express micrograms and "mg" be used for milligrams on product labels.

Internationally recognized standards of scientific notation are not acceptable to the U.S. FDA. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
