Talk:Mya (unit)

message: why did someone decide 'ma' is better than 'mya'?
mya is simple direct, to the point. only problem is its in english...
then again, why not have the 'ago' translated into latin or whatever.
it makes no snse to just say 'xyz happened 500 years'.   —Preceding unsigned comment added by Decora (talk • contribs) 16:36, 30 December 2008 (UTC)

thread_title:  mya vs ma 

message: The title should be changed to Ma (unit). Outside of the english speaking world nobody uses Mya, the international convention is Ma (mega annum). Now this is an english encyclopedia, but the term used in literature is Ma, because most of the authors are not native in english. Let's stick to the scientific conventions.

thread_title: Title

message: I agree with woodwalker (comment above). Besides, English-speaking scientists use "Ma" rather than "mya" (e.g., see  Gradstein et al. 2004 - A geologic time scale 2004, Cambridge University Press). I never met "mya" in my professional career, so I suppose it is now a word in disuse.

message: The result was merge into Annum. -- LeadSongDog (talk) 20:35, 1 May 2008 (UTC)
replies: text: I agree: there should be one article, in which the suffices M- (mega), G- (giga), b- (billion), T- (tera) and k- (kilo) are linked and explained. Myr/My is the same as Ma. Ma is internationally used, Myr only in the English-speaking world, so Ma would be a better title for an article (specialists would use Ma). Even better, I would use annum as a title for the merged article. Woodwalker 13:35, 10 August 2007 (UTC)
replies: text: There is actually a difference in the way specialists use Ma and Myr. The first is used for elapsed time, as in, e.g., "The beginning of Mesozoic is at ca. 250 Ma" - that is, millions of years ago. The second is for time as a measure unit, as in "The duration of Mesozoic is less than 200 Myrs". Without a single article explaining these things, people would never get oriented in these complex issues. --Kaapitone 08:58, 15 September 2007 (UTC)
