The original question was how to convert 19 miles to km.
First decompose it into a sum of Fibonacci numbers:
19 = 13 + 5 + 1
Then find the next Fibonacci number for each one of them:
13 -> 21
5 -> 8
1 -> 2
Then sum them up to get the result in kilometers:
21 + 8 + 2 = 31km
Which is within 1.36% of the correct answer (the correct answer is 30.57km.)

- jonp 17y agoI thought the OP was alluding to the slight ambiguity because 1 appears twice in the Fibonacci sequence. You could interpret the approach two ways and do either 21 + 8 + 2 = 31 km or 21 + 8 + 1 = 30 km. Happily these span the correct answer of 30.55km.
- gjm11 17y agoIn this situation I tend to pretend that 1 -> 1.5. (Or, indeed, 1.6, but generally that looks like claiming more accuracy than is really justified.)
- kscaldef 17y agoOkay, but you could also say 19 = 20 - 1 then multiply by 1.6 20 -> 32 1 -> 1.6 and get the estimate 19mi = 30.4km, which is even closer and seems rather easier to me than figuring out a set of Fibonacci numbers which sum to 19.
