Most people who deal in imperial units know off the top of their head that 1/3 of a mile is 1760 feet. They don’t have to calculate it. After a while you see that number come up often enough and it’s committed to memory.
I’m not saying that metric isn’t better, it is, and I wish we would hurry up and switch to it. I’m just saying that the numbers involved aren’t a handicap once you have worked with the imperial system for a while. If you have a set of sockets that you work with every day, you know instantly that 3/8” is bigger than 19/64”. Hell, even 5/16” is bigger than 19/64”.
And, you must admit, 333 meters is not one third of a kilometer. It is one third of 999 meters. The number 5280, for all its awkwardness, is beautiful in the sense that it is evenly divisible by 12, Meaning that it can be exactly divided into quarters, thirds, or halves without a fractional part.
Oh, what’s interesting about a nautical mile is that it wasn’t originally even based on a number of feet or meters or whatever. It represented one minute of latitude (60 minutes in a degree type of minutes). Since the earth is an oblate spheroid instead of a perfect sphere, that meant that traditional nautical miles varied based on your position until they were standardized it in 1929.
I think it’s about 1.85 kilometers, but I wouldn’t have occasion to do the conversion because I’m a landlubber.
It’s a lot of memorization that I simply haven’t done and won’t ever have to do.
The fraction reduction doesn’t help intuitive thought. If imperial operated on ‘significant digits’ and marked any set or document with a 64th always as 64ths, as in 16/64ths, I’d be more on board.
We just need to replace out base 10 system of counting with base 12 and we’d get the best of both worlds!
Yeah, absolutely, I’m not arguing in favor of making everyone do the memorization, I just think it’s interesting that it occurs after enough exposure.
I’ve often thought that if we’d have evolved to have 6 digits instead of 5, we might have adopted a base 12 system and made fractional calculations a lot easier.

How would you convert to e.g nautical miles?

I gotta say, you make some fair points.
