Use of abbreviation Greek "gamma"

I believe that the Greek letter "gamma" was sometimes used alone to represent micrograms. Assuming that I am correct about this, I suggest mentioning this as a deprecated abbreviation. Thomas.Hedden (talk) 13:28, 30 April 2009 (UTC)[reply]

I confirm, in molecular biology I have seen people using γ for micrograms, for instance to indicate a quantity of dry oligonucleotides in a tube, or to indicate a concentration together with another informal abbreviation for microliters, λ. For instance, 1 µg/µl was written 1 γ/λ.134.160.83.73 (talk) 02:46, 26 March 2010 (UTC)[reply]

Presence on Do Not Use List

Is mcg still the preferred medical use? Do-not-use list says that mcg is on the United States Do-Not-Use list. If this is the case, what is now used to indicate micrograms? 24.247.213.106 (talk) 18:29, 19 May 2012 (UTC)[reply]

The list you link to is just a list of abbreviations used in medical prescriptions and hospital orders. Only the ones highlighted in red or orange are not recommended for use. Ormewood (talk) 23:21, 21 April 2014 (UTC)[reply]

Confusion

NIST, under the U.S. Department of Commerce, advocates the use of SI units for everything bought and sold. It should be noted that the U.S. Dept. of Commerce and the U.S. FDA are not on the same page. I was sure that mcg meant milli-centagrams (an obvious compounding of metric prefixes, the very thing NIST warns against in SP 330), but I see now that it could be a new creative abbreviation for "mc"="micro" grams. Just awful. — Preceding unsigned comment added by DavidDHaynes (talk • contribs) 17:34, 6 September 2019 (UTC)[reply]

In Europe, SI units are mandatory for economic, public-health, public-safety and administrative purposes. However, for medicinal products the abbreviation of microgram varies. The European (EMA) guideline for medicinal products is that for safety reasons it is important that ‘micrograms’ is spelt out in full and not abbreviated. However, in certain instances where this poses a practical problem which cannot be solved by using a smaller type size then abbreviated forms may be used, if justified and if there are no safety concerns. Which abbreviation varies between European countries. In most countries it is 'µg', in other countries 'mikrog', or 'mcg'. France does not accept the use of any abbreviation.

microgram/ml

I have seen microgram/ml in several places, eg https://pubmed.ncbi.nlm.nih.gov/12187818/, Even the American Chemical Society use it https://pubs.acs.org/doi/pdf/10.1021/acsreagents.6006 and then abbreviated to mcg/ml when it would be much more sensible and correct to use mg/L. 194.207.86.26 (talk) 06:29, 23 August 2021 (UTC)[reply]

Examples Section?

I don't know enough about micrograms, but I really enjoyed the Micrometer page's Examples section - would anyone be interested in adding something similar here? I just don't know where to easily find resources like that, I might do my own attempt later but I think this would be great to have. --BlinksTale (talk) 17:44, 26 January 2023 (UTC)[reply]
