(moderation:
I understand that credits are a measure of the work your machines have done for the project.
But what is one credit equivalent to? Are they added up based on the number of FLOPs completed? Or the number of tasks?
If anyone knows, let me know.

In the documentation "a credit" is defined as "A BOINC project gives you credit for the computations your computers perform for it. BOINC's unit of credit, the Cobblestone (named after Jeff Cobb of SETI@home), is 1/200 day of CPU time on a reference computer that does 1,000 MFLOPS based on the Whetstone benchmark".
This has, during the years, been adopted/calibrated/changed etc. by different projects so that it no longer holds true to the initial intention. Different projects has chosen different path concerning credits, some try to uphold the initial intent while others use credits (inflation) to attract volunteers.
Here at Eintstein@home the credits are supposed to be calibrated to how much work (ie FLOPS to complete) there is in a task, within the project and not necessarily comparable to other projects. The admins has tried to calibrate this over time as different searches has been run, but it's not always easy to understand how things actually works.
Is there any specific reason you ask?

The main reason I ask is just curiosity. I was wondering if there was a way to work backwards and find how many FLOPs each of my computers has crunched based on its number of credits.

If you go to your account and look at the top right corner of the credit graph you'll find a link, certificates, that generates a certificate that among other things shows you the number of FLOPs. Not sure how accurate it is though.
