230 years since British pirates robbed the US of the metric system

Distances are in meters if they are short, miles if they are long, Leeds will be 275 miles away from your gas station that would charge you by the liter so would be most other liquids unless they are milk or beer, then you’ll get a mixtures of metric pipes with inch threads and inch pipes with metric threads, when you buy a property the land would be demarcated in acres, build up area in square feet and priced in meters squared… and when you over eat because of all the stress of having to memorize 1000 different measurement units your doctor would tell you that you gotta drop a few stones…

  * Road distances are measured in miles.
  * Drinks are ordered in pints.
  * People measure height in feet/inches and weight in stones.

I believe they are now technically defined in mm, but obviously it's still based on fractions of an inch. In my view, there aren't any truly compelling reasons to switch from BSP to something based on natural metric measures.

On the other hand, if we were to replace these pipe fittings with metric, we'd end up with a mixed system for realistically at least a century, if not a lot longer due to how long pipe systems last. The complexity (and also, in some cases, danger) of having to maintain both systems for so long would be incredible.

It's similar to how in flying, we still use feet/flight levels, and actually a few places have migrated from metric to the more conventional imperial system.

Imperial pipe fittings are pretty common across the entire world, in fact. I think most countries outside of UK/USA use BSP (often by a different name), but NPT is also sometimes used - and even BSP vs NPT is a huge pain.

Take the meter, the group setting up the metric system was searching hard for something that was close in size to a yard so they choose 1/10_000_000 the distance from the pole to the equator. nothing wrong with that, but it is not really better than any other arbitrary unit, and with the better defined ways to calculate it(now defined as 1/299792458 of a light second), just as random.

Or celsius, base it on 100 units between the freezing and boiling points of water, not a terrible thing to use, however with the later discovery of absolute zero, they needed a scale that used that, but did not try to redefine the measurement system to include absolute zero, so now you now have this really awkward 273.15... degree difference between the two scales, the nice scale that starts at zero has no other auspicious points to calibrate it at, and the scale with nice points does not start at zero. they could have made their new scale 100 degrees between zero and the freezing point of water, but that would have re jiggered every other derived unit, so understandable that they did not.

Personally I think an si system set up around base twelve would kick ass, what would make it even better would be to replace our base ten number system with a base twelve one, 10 is kind of a poor number in terms of fractions possible. 2 is fine but nobody wants to use 5, things just get awkward when you use 5. nether one is ever going to happen but it is fun to think about our assumptions when it comes to counting and measurement.

But I would happily adopt a base 12 number system with base 12 units. Let’s say we use X for 10 and Ǝ for 11, 134 would be 1Ǝ, 24 hour clock a 20 (base 12) hour clock
