Yocto

Jun. 13th, 2013 12:14 pm
I've been wondering recently where the word yocto as in "Yocto Project" might come from and recently I came across it's use as a prefix indicating size.

I can count down by thousands as, "milli-", "micro-", "nano-", and "pico-", but that's as far a I go. However, if you want to go further you can with "femto-", "atto-", "zepto-", and "yocto-". yocto is from the Greek for eight, because it's (10^3)^8, i.e., 10^24. The y was prepended so that there would be some uniformity in the naming scheme. The number nine in Greek is something like ennea, maybe the prefix for 10^27 could be "xena-"?
