#lifeprotip - jak szybko i dość precyzyjnie radzić sobie z konwersją mili na kilometry i odwrotnie.

The Fibonacci Sequence, for those who don't know, is this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, .... Starting with 1, the two >neighboring numbers added up equal the next number. One interesting aspect of these numbers is that their ratios all approach >being what is called the golden ratio, 1.618....


So, for example, 3/2 is 1.5, 5/3 is 1.666, 8/5 is 1.6, 13/8 is 1.625, 21/13 is 1.615, 34/21 is 1.619, etc.


So what does this have to do with kilometres to miles? Well, the ratio of km to mi is 1.609 to 1. Since 1.609 is so close to the >golden ratio, you can use the Fibonacci numbers to convert between kilometres and miles! For example, 5 km is quite close to >3 miles (3.1 mi). 8 km is almost exactly 5 miles, 13 km is 8 miles, 21 km is 13 miles, etc! I think this is awesome.
