Talk:Micro-

message: "In circumstances where only the Latin alphabet is available, the SI standard allows representation of the prefix using the letter u as in um for µm, or uV for µV." This assertion must be sourced or deleted. I didn't find this statement of this in SI Brochure (http://www.bipm.org/en/si/si_brochure/) so I think this use is not allowed officially. Please provide a source or it will be deleted. Armando82 10:47, 20 April 2007 (UTC)

replies: text:  The use of u or U as the substitute for µ is specified in ISO 2955. See Table 2. Kimura Aichi (talk) 12:14, 24 October 2008 (UTC)
replies: text:  As of 2021 „ISO 2955:1983 INFORMATION PROCESSING — REPRESENTATION OF SI AND OTHER UNITS IN SYSTEMS WITH LIMITED CHARACTER SETS“ is withdrawn. Also, the article does not state, that this usage is for „LIMITED CHARACTER SETS“, making the info misleading.  — Preceding unsigned comment added by 94.26.77.227 (talk) 11:44, 11 February 2021 (UTC)
thread_title:  Non standard prefix  [[u]] 

message: I think that the move from Micro to micro- was good, but why is there a  tag?  The full name is capitalized at the beginning of a sentence just like normal words are, and microfarad, micrometer, etc are capitalized like other words.
Obviously the abbreviations must keep their case even when it would otherwise be changed, but not so for the full form.  (That is, unless someone has a good reference -- for example using "microfarad capacitance is desired." instead of "Microfarad capacitance is desired." or an explicit discussion of this issue.)

thread_title:  Lowercase? 

message: I’m changing μ to be in a roman (not italic) font throughout this article, in accordance with the ISO standards linked at the bottom, which are presumably authoritative. I see no source justifying their consistent italicization. Obviously when used in a context like: “the symbol μ for micro means...”, the italics are appropriate. –jacobolus (t) 18:47, 10 May 2010 (UTC)
replies: text: It may also have been a mix of the legacy µ sign which is often rendered in italics even if not asking so, and the greek letter μ, which behaves as expected. The legacy µ sign should be avoided for this and other reasons, as mentioned elsewhere on this Talk page. M Killian (talk) 16:04, 9 March 2020 (UTC)
thread_title:  italics? 

message: Where did the bit about mcg being used in Pharmacy come from? I checked the list, and it states that mcg is NOT acceptable. http://en.wikipedia.org/wiki/List_of_abbreviations_used_in_medical_prescriptions  --74.215.62.191 (talk) 10:59, 2 August 2012 (UTC)
replies: text: I fixed it. The confusion arose because the Joint Commission recommendation is to use either "mcg" or "microgram", whereas some other organizations want only "microgram" (best practice). The "mcg" abbrev is in common use in health care. — ¾-10 23:34, 2 August 2012 (UTC)
thread_title:  Mcg used in pharmacy? 

message: Why does this article use U+00B5, given that U+03BC is the preferred form? The SI units table uses U+03BC. —StuartBrady (Talk) 20:38, 25 August 2015 (UTC)
replies: text: In the current version of this page we use the greek letter everywhere, except where the legacy sign is meant specifically. Thanks for pointing at the issue, which has been solved in the mean time. M Killian (talk) 16:04, 9 March 2020 (UTC)
thread_title:  Unicode character used in this article 

message: just not much system to this wording chosen for the degrees of magnitude, & not much mnemonics, and for those that dont hav english or, especially, latin as their first language??? such inefficiency for a group of people that hav t remember so so much!! so much of science has turned into this, and its understandable with brick by brick things added on, yet somday sombody is gonna have to fix it  — Preceding unsigned comment added by 204.10.126.202 (talk) 00:38, 8 March 2016 (UTC)
replies: text: What is especially bad is that the system of using Greek prefixes (deka, hekto, kilo) for multiplication (x10; x100; x1000) and Latin prefixes (deci, centi, milli) for division (1/10; 1/100; 1/1000) has been forsaken.  — Preceding unsigned comment added by 180.200.153.211 (talk) 06:58, 6 August 2016 (UTC)
thread_title:  another badly designed critical element of science 

message: FWIW, concerning this edit: see Unicode Technical Report #25, page 11:  So clearly they created the special symbols for implementations where the Greek (resp. Latin) letters are unavailable, but still prefer the Greek (resp. Latin) letters where they are available. As they are available here, and as most keyboards that do have a mu, provide the Greek letter, the edit seems on the mark.

thread_title:  Greek mu vs micro mu 

message: Is there a differance? Are those coded by different unicode characters? Which unicode block does the latter come from?
Which is is preffered, the Greek alphabet character from the Unicode block, or the dedicated character from a block I am not yet aware of?

thread_title:  Greek letter μ or legacy symbol µ 

message: does anyone have a source for the use of "mc" as a replacement for "μ"?  I've never seen it used, and the only sources I can find that mention it look unreliable.
