It blows our hivemind that the United States doesn't use the ISO 216 paper size standard (A4, A5 and the gang).
Like, we consider ourselves worldly people and are aware of America's little idiosyncrasies like mass incarceration, the widespread availability of assault weapons and not being able to transfer money via your banking app, but come on - look how absolutely great it is to be European:

Instead, Americans prostrate themselves to bizarrely-named paper types of seemingly random size: Letter, Legal, Tabloid (Ledger) and all other types of sordid nonsense. We're not even going to include a picture because this is a family-friendly finance blog.
The gallon of milk makes it incredibly easy to divide it into quarters. That makes it easy to simply double things - 2 pints = 1 quart. 2 quarts = 1/2 gallon. Two 1/2 gallons makes 1 gallon. This dates back to the days when you went to the market and told the seller that you want 1/2 or 1/4 of that container of whatever was in that container. Simple math for simple needs.
Your 1/4 of a pound of butter or one stick, (again simple divisions for a simple use), is marked with rough marks of tablespoons for cooking if you are using such measurements. But you are quite free to ignore them if you are using a scale. Not really any issue.
Yes, in the US travel distances are measured in miles. But that slowly becoming meaningless also. People, (no matter the units used to measure the psychical distance), care more about "how long does it take to get there" rather than the actual distance traveled. But, you are free to push a button and switch to kilometers if you choose.
Measuring height and weight in feet and inches and pounds is pretty much the only thing the medical system uses US Customary for. And I can't imagine the sheer number of man hours and cost it would take to go back and convert all those medical records to centimeters and kilos. Somethings are just not worth the effort and cost for a minor data point that only matters only as a long term trend. (just like a single blood pressure is a meaningless data point but over a year may reveal a trend or not)
Each measurement system, US Customary or Metric, has it's own advantages and disadvantages. To think one is better than the other is a chauvinism based on what you are most familiar with and nothing more.
I mean, a liter is very close to a quart, so it's not like we'd be asking people to adjust their mindset completely. And ditching US measures means we could finally, once and for all, dispense with the nonsense of having a dry and a wet "cup" measure.
As for converting records, well, it would be trivial to display a converted value in whatever EMR system a practice uses while noting the values are converted and allowing display of the uncoverted data for validation. (Which brings us to the EMR discussion.)
How did you reach the conclusion that liters can't be halved or quartered? You could call 250ml a 'quart' if you wanted to.
Metric butter also has markings on it.
Those medical records should be stored digital anyways, and then it's a matter of a few man hours to tell the computer to convert them.
Imo metric can do everything US customary can, but not the other way around, because it's missing the simple conversions. But that's it. Everything else is same same but different
I never said that you can't divide liters into fractional parts. Reread the quote again.
But for demonstration - what's easier to think about 250ml or 1 quart, (a whole unit number or if you prefer 1/4 of a gallon)? A fractional based measurement system was the first type of measures invented by people precisely because it WAS simple for everyday use between sellers and buyers. The US has just kept using it for simple everyday needs. It's neither better or worse than your 250mls, it's just different than what YOU are probably used to. To me, it doesn't matter. I'm fine with either measurement.
The majority medical records are available electronically. But that does not provide the base security of also storing written records. Networks go down, networks get hacked and not all places in the US can have or trust that those records will be available electronically 100% of the time. Paper ain't going away anytime soon.
I suppose we could go off into the weeds a bit and talk about how US Customary thread pitches made for fast to produce, smaller, and cheaper machine tools vs their same metric counter parts. And how it helped make the US into the manufacturing powerhouse it became. And how those same US Customary threads are a just a little bit stronger than their metric counterparts. But you would probably not understand much of it and your eyes would glaze over pretty quickly anyway. But these days it's merely a matter of G20 or G21 - The machines don't care, why should you?
Both measurement systems can do exactly EVERYTHING the other can do. Somethings can be easier in one system than the other, but it's far from a universal idea that one is 100% better than the other. Personally, I prefer using the metric system. But I don't get hung up on it. I will use whatever measurement system best meets the needs for the job at hand or is requested/required.
In the end, the metric system IS the official system of the US. We just didn't force a hard adoption date on it. But we use it everyday all day and don't even think about it. Now if you will excuse me, I need to buy a 750ml bottle of Old Grand Dad bourbon Bonded, so I can myself an Old Fashioned cocktail later today while I'm smoking a pork loin........
