Hey all.  Hope you can help me with a fun little app project i've been working on.  I just released my first version of an iphone/ipad app called "Geek Units."  Which takes real units and converts them into fictional units from famous science fiction genres.  I have galactic credits and trogan meters so far from Star Wars.  Can anybody think of any other units of measurement?  Also, does anybody have any thoughts on the conversion rate of the galactic credit into US Dollars or Another currency?  Would love some help from the community.  THANKS
