Sometimes when folks ask me how big the battery is I say 540 yotta electron 
volts.  
Some say “hmmm” and nod knowingly...

I think it is also  .945 micrograms if I did the conversion properly.  I think 
that  is probably the coolest unit of measure for energy.  This car has a 1 
microgram battery.  A tesla model S P85D has a bit over 3 micrograms.
