I am not bragging, just telling a truth: the one industry that excels at the correct use of SI symbols on its labeling and packaging is the pharmaceutical industry.
However, many healthcare professionals do not follow suit. As Jim mentioned, they might use "gm" for "g," or "mgm" and "mgs" for "mg." Then there is the problem with the recognition of the Greek letter "mu" for the SI prefix "micro." Due to its possible confusion with "m" when handwritten, the Joint Commission years ago insisted that the expression "mcg" be used instead, so packaging ends up bearing either notation. > On Oct 20, 2016, at 22:03, James <[email protected]> wrote: > > The conversion exercises you mention (e.g., centiliters in a dekaliter) are > all within one system.
