Why bother with plain old inches or centimeters, when you can measure things in a unit based on the fundamental constants of the universe!

I'd like to refer to these tick marks using ginormous metric prefixes, like
how you'd say that the universe is 430 petaseconds (Ps) old. Unfortunately, the
largest metric prefix, yotta (Y), is only 10^{24}, and this ruler shows
much larger aggregates of Planck lengths than this. My only alternative is to
string together two metric prefixes, with the understanding that they'll
multiply together, e.g. kiloyotta would be a thousand yotta, or
10^{27}, and megayotta would be a million yotta or 10^{30}.

So ... the big tick marks on the ruler are gigayottaPlanck-lengths
(GYl_{P}). The little tick marks would be increments of 100
megayottaPlanck-lengths (100 MYl_{P}). For comparison, a football field
is a little over five terayottaPlanck-lengths (TYl_{P}) long.

- Uh oh, I think I had one too many large pizzas. I'm up to 4.585 gigaPlanck-masses. At my height of 113.2 gigayottaPlanck-lengths, that's a body mass index of 29.8. I'd better cut back on the cheesecake!

- The Planck force bathroom scale!
- Because telling people you're 4.585 x 10
