There is a Wikipedia article of the same name

I was not a contributor to the WP article. This article was written and formatted from scratch. It has some content from the WP article and it is much shorter because I thought that the WP article was much too wordy, got into too much detail and went off on some unneeded tangents.

Section out of place ?

The Summary of large number names section seems out of place, since the article presents ppm, ppb and ppt. Should we keep it? Olier Raby 22:43, 14 October 2008 (UTC)

Thanks for your comment, Olier. I had two reasons for including that section in the article:
  • The content of the table in that section is, to the best of my knowledge, not available elsewhere on CZ, so I could not simply link to any article discussing that content.
  • Since this article discusses parts per million, parts per billion, and parts per trillion, and alerts readers to the different definitions of million, billion and trillion in the U.K, I reasoned that it would be well to point out all of the different definitions of large numbers including Europe. In fact, the table should probably include India, China and Japan ... if I could find a reliable source.
If you or anyone else would like to create a new article devoted to the subject of "large number names", then this article could simply link to that article and the section we are discussing could certainly be deleted then. Regards, Milton Beychok 02:36, 15 October 2008 (UTC)
