And many of the conversions between metric and imperial align with the Fibonacci sequence on any order of magnitude. 130km/h is roughly 80mph simply because the fibo sequence has 8 and 13.
Obviously not an emergent property but shows how these things were designed.
- thfuran 1y agoI don’t think any common conversions fall near there other than miles->km. It’s certainly not the case that the systems were designed to have the golden ratio as conversions between the two.
- rich_sasha 1y ago1 mile = 1,000 [double] paces of 0.8m each = 1,600m 1m = 1e-10 times half-meridian from the North Pole to the equator, via Paris for a croissant, apparently. So kind of a coincindence... But a very neat one. Meanwhile, ratio of adjacent Fibonacci numbers converves to some expression involving sqrt(5) which is approx 1.6
