Do you remember the Fibonacci sequence? You can use it to convert miles to kilometers .

2 mi ~= 3km

5mi ~= 8km

8mi ~= 13km

13mi ~= 21km

And so on.

Wait, is this true until its not or is it true forever as you go higher in the sequence?

[โ€“] liam_galt@lemmy.blahaj.zone 13 points 1 year ago (2 children)

It's true forever. The Fibonacci sequence used in this way converges on the golden ratio, which is close to the conversion of km and mi.

Someone already replied with a graph, but I also got curious and checked for some higher numbers. Sure enough, it held up.

For example:
832,040mi => 1,346,269km (actual: 1,339,039km)

So are you telling me that the inventors of the mile were using the golden ratio?

[โ€“] Maya@lemmy.fmhy.ml 3 points 1 year ago

We wish they were that cool, the inventors of the modern mile were more concerned about land measurements. A square mile is 640 acres. Which neatly can be cut into quarters 3 times. 160, 40, 10.

Just a neat coincidence
