My friend showed me this website, and it takes you all the way from 10^-35m. (that means 34 0's after the decimal point) to 10^26 x 9.3m.
The website can be found here, and while it is rather cartoony, the information provided is accurate. Yes even the 7 meter earthworm. The largest confirmed earthworm was 6.7 meters long, and there have been unconfirmed reports of much larger earth worms.
Even with all of that information clearly in front of me it's difficult for me to comprehend it all.
