       Huh.So, just now I learned that you can convert miles to kilometers with the Fibonacci sequence?A mile is 1.609 kilometers.The Golden Ratio, the ratio between Fibonacci numbers as they get large, is 1.618. So, within about 1%. And large doesn't need to be that large, it's actually pretty accurate from about 8 onwards.1 1 2 3 5 8 13 21 34 55 89 etc etc5 miles is 8 km. 21 miles is 34 km.89 miles is 144 km. etc etc.Kinda neat IMO.

       @mhoye One of today's lucky ten thousand! 🎉I learned this running cross country in high school, because at least at that time and place, HS men's courses were 3 kilometers or 5 miles, and HS women's courses were 2 kilometers or 3 miles, which was still sufficiently close to notice the start of that series. 😀

       @mhoye neat but imagine if places just stopped using miles. 🤔

       @justin @mhoye …and hours.A modest proposal:A UTC day is 86.4 ±0.001 ks, damn it! (Kiloseconds = 16.6̇ minutes ~= quarter of an hour).Speeds of road vehicles, for example, are measured for two purposes: traffic safety and estimating time to get places.For safety purposes (e.g., speed limits) the distance they'll go in the next 3600 seconds is irrelevant, it's the distance they'll go in in human reaction times and braking times which are of the order of seconds (i.e., more than 0.1 s, less than 10 s) so m/s (metres per second) are more relevant.If you measure times of day in ks then m/s = km/ks so the same numeric value can be used for both purposes.And, while we're at it, we can get rid of the kilowatt·hour so measure electricity consumption in MJ (1 kWh = 3.6 MJ). That'd save a near-infinite amount of painful and unnecessary confusion.

       @mhoye you can also use the subway stations on the midtown portion of the 6 line in Manhattan to roughly convert from Fahrenheit to Celsius
