Ah yes, I always remember the Fibonacci sequence and totally wouldn't find it harder to calculate than just doing the conversion the regular way

/sarcasm

"Remember"? Do you also remember all the digits of π?

It's defined as F(0) = 0, F(1) = 1 and F(n) = F(n - 1) + F(n - 2). Which makes more sense than imperial units.

Or I could just do 1.6 km ≈ 1 mile whenever I need to convert from the standard that I use, Metric, to Imperial

Far far far simpler

Edit: I'm not American, I use sensible units, SI Metric

Edit edit: I do fully have dyscalcus, mostly only effects "scary" looking maths, so no, your suggestion doesn't help

I know from running that 5k is 3.1miles so I just go from there

But woudn't you only need the 3 = 5 part?
