Please don't let's have a referendum - the entire planet will go back to imperial - in the UK at least there's still a huge, possibly majority, definitely passionate, group that prefer imperial units. Hence we still have one foot in mph and pints. There's talk of it happening regardless, as without the EU there's no requirement here to use SI units - and one pundit even suggested a return to pre-decimal currency. Either way, people tend to value tradition more than progress or rationalisation. Having a system of weights based on the weight of a grain of emmer wheat is preferable to plenty of people, who don't have to write code or multiply weights or do science, and just want familiar human-scale units. Hell, I'm sure plenty of the aforementioned would prefer imperial too, for the same reason.

> There's talk of it happening regardless, as without the EU there's no requirement here to use SI units The EU did initially have the goal of getting rid of all non-metric units, but gave up in early 2000s since the UK was opposed. A part of me could see an UK-in-the-EEA being forced to switch to metric, if the EU were to go full metric (with the UK not having a vote of course), and that's applying to the EEA (incl UK). And if the UK were to apply to rejoin the EU, I suspect metricification would be one of the requirements of reentry. So the brexit vote might increase the chance of the UK going metric. :)

> Either way, people tend to value tradition more than progress or rationalisation. Don't get me wrong, I'm pro-metric, but the old units are not entirely irrational. For instance, there are 12 inches in a foot, which may seem odd, unless you need to measure 1/3 of a foot. You might argue that the foot represents a future society that uses base-12, while metric lags behind, in the not-as-divisible base-10 world. It's also interesting to note that on rulers, in the US anyway, each inch is subdivided into 16 sub-units, so measurements are usually given as, say, 3 3/16 inches rather than 3.1875 or (rounding) 3.2 inches. In other words, hexadecimal rather than decimal.

  So, 12 inches in a foot isn't odd because it makes it easier to measure a third of a foot, but, apparently, people need one eighth or one sixteenth of an inch way more often than one third, so the rational thing to do is to divide an inch in 16 parts, not 12? Also, people rarely need a third of a mile, so why bother giving that a name or even making that an integral number of yards? But hey, if you happen to need one eleventh of a mile, rejoice: that's 160 yards, and one eighth of a mile, apparently, is used so much that it has its own name. Correlation is not causation, but chances are a third of a foot is more popular because there are 12 inches in a foot, not the other way around.

  Imperial units would be a lot more defensible if they were consistent. But just in your example we've got things being divided into 12 and 16 parts, and many other random divisors are common. I'd be onboard with a system of units where the divisor is always constant, but having it random is annoying. Fortunately there is a system of units where the divisor is always constant - SI! Yeah, it's 10 instead of 12, but it'll have to do.

    I agree that the Imperial system is a mess. 5,280 feet in a mile? But my point is that people who prefer old units are not being entirely irrational, or averse to change. It's just that for their particular use case (making human-scale furniture out of wood, for example), the Imperial system works pretty well, and perhaps better than the base-10 metric system. If they had to spend their days converting between acres and square feet (43,560 of the latter go into the former, by the way), they might be more inclined to switch to metric.

      One thousand paces in a mile, where each pace is two steps. A property of the US customary units is they tend to be more optimized for specific uses at a given scales, with little thought given to changing scales. Metric units make conversion easier, at the cost of often less suitable for use at scale - how many steps does it take to go a kilometer?

> in the UK at least there's still a huge, possibly majority, definitely passionate, group that prefer imperial units. Erm... no. Anyone over 60, probably, but young people here don't even have any idea what a pound or ounce is.

  It's slightly more confusing for young people over here -- we mostly deal in metric, but we still do have pints of beer (from the tap -- the bottles are 330 or 500 ml), miles, and we measure ourselves in feet, inches, and stone (although you do run in to people who use cm & kg, so that varies a bit)

    Not only that, but draught beer and cider have to be sold in pints (or 1/3, 1/2 or 2/3) while nothing else is allowed to be, so a "pint" of coke is supposed to actually be 500ml, and spirits are in multiples of 25ml or 35ml.
