For consistency with the current SI units, the prefix should probably be derived from "nona" which is Latin for nine. 10^27 = (10^3)^9. 10^24 = (10^3)^8 is yo

For consistency with the current SI units, the prefix should probably be derived from "nona" which is Latin for nine. 10^27 = (10^3)^9. 10^24 = (10^3)^8 is yotta which is derived from "y" + "octo". They added the "y" to prevent the "o" from being mistaken as 0. http://lamar.colostate.edu/~hillger/si-prefixes.html http://lamar.colostate.edu/~hillger/si-prefixes.html http://members.optus.net/alexey/prefSI.xhtml http://members.optus.net/alexey/prefSI.xhtml http://www.wordinfo.info/words/index/info/view_unit/1409/ http://www.wordinfo.info/words/index/info/view_unit/1409/
