Heres another quizlet set that I made: https://quizlet.com/286400676/fermi-facts-flash-cards/

It's essentially a copy of the Wikipedia "orders of magnitude" pages for stuff like mass, length, energy etc. Those pages are really useful.

quick tip: don't just use the power of ten, also include the coefficent. For example the mass of a electron is 9.1*10^-31 kg not just -31, and would round to -30 if it just asked for mass of a electron

Does anyone know of an accurate number for the number of grains of sand in the world? According to google it's 10^19, but google also says the Sahara along has 10^24 grains... so.... Can anyone help?

### Resources

Are there any good textbooks/resources (paid or free) for studying Fermí questions in general? Also, are there any such resources that list all of the pieces of information that it is helpful for study to prepare for this event (population of NY, size of a cell, etc.).
Thank you.

Thank you.
Just take as many tests as you can. I've personally found the best way to do fermi is take tests, and after finishing the test, go over anything you got wrong (or sometimes even if you got it right), and figure out (and make sure you really understand) how to get the actual answer. Google whatever you don't know and memorize that so if you ever see the infomation again, you'll get it right. Tests generally ask similar style questions, so just get to know values that keep showing up.

Almost all resources i've found online has been mostly useless (fermiquestion.com was a good starter tool, rip that). Orders of magnitude on wikipedia is ok I guess but alot of the info is mostly irrelevant and is missing most of the more useful info. Idk about any possible textbooks, but i've never used them for fermi.

I use 19 because pretty much every test says 19. If it asks specifically for the sahara... im not sure what to go with.

I will take a guess that the top scores were in the 60-65% range. Fermi is pretty consistent.

Wow, above is the true Fermi Master
