In case you wondered where they came in the list like I immediately did:
- quetta Q 10^30
- ronna R 10^27
- yotta Y 10^24
- zetta Z 10^21
- exa E 10^18
- peta P 10^15
- tera T 10^12
- giga G 10^9
- mega M 10^6
- kilo k 10^3
- hecto h 10^2
- deca da 10^1
- ——
- deci d 10^−1
- centi c 10^−2
- milli m 10^−3
- micro μ 10^−6
- nano n 10^−9
- pico p 10^−12
- femto f 10^p−15
- atto a 10^−18
- zepto z 10^−21
- yocto y 10^−24
- ronto r 10^−27
- quecto q 10^−30
I noticed recently that a Linux command mentioned in its manpage that it supported Q as a bit prefix and I had to stop to ponder the utility in encoding a million-billion Terabytes.
But did they mean Quettabytes or Quebibytes? Because the difference is only around 250 000 times the size of the Internet.
Or, in other words, around 244 kibiInternets.
Bah, that's just a rounding error!
I'm going to start giving my height in quectometres
Googol 10^100.
(Not sure if that's official prefix.)
As far as I remember it isn't, it's just a named specific large number, like Avogadro's number or Graham's number.
