      Logical, mathematically convenient, but not practically convenient. Without a measuring tool, there’s no good way to estimate anything besides a centimeter.

      Every imperial unit of measure can be estimated whilst naked (but preferably clothed).

      An inch is your distal thumb phalanx. A foot is your foot. A mile is, or was at one point, roughly 1,000 paces.

      The weather can be estimated by going outside. Is it too hot? It’s in the upper third of the 100 degree scale. Too cold? Lower third, might snow. Cool enough to fully dress, but not too cold, right in the middle.

      A healthy, big person is about 200 lbs. A very small person is about 100 lbs.

      Converting between these units is useful in science, which is why science uses metric. But you could live your entire life on earth and never need to know how many distal phanages are in 1,000 paces. It literally never comes up. Who cares?

      It’s why units are divided into fractions, rather than into a decimal system.

      By the way, the only reason we use a base 10 numbering system in the first place is because we have ten fingers and it was easier for early mathematicians to count. But I digress.

      If you’re dividing a length of rope, and all you have is the rope, it’s simple to divide it in half, and then half again, and then again in half. You could even divide into thirds, if you were feeling frisky. You just fold it over itself until the lengths are even. There are two friendly numbers that are difficult to do that with, though. Can you guess what they are? If you guessed 5 and 10, you nailed it, good job.

      Same with piles of grain or hunks of beef or chunks of precious metals.

      But what about units of volume, you ask? I don’t have a part of my body that holds roughly 8 oz of fluid to pour out. No, for that you’ll need a cup. Just a cup. Not a graduated cup with a bunch of little lines down the side. 1 cup. Or half a cup, or a third, or maybe a quarter cup. Again, easily divisible for easy measuring without any special tools.

      But a gallon, you protest. A gallon is 16 cups! What the fuck is 16 cups good for? Why not 10 or 100, or create a decigallon for simple math? Because 16 can be divided in half 4 times. Measuring out portions of the whole is as simple as pouring out equal portions into similarly sized containers. Divisible numbers are easier to use without graduated equipment.

      And that’s why time is measured in 24 hours, each hour is 60 minutes, each minute is 60 seconds. There’s a ton of history there, and we’ll ignore for this discussion the inaccuracy of measuring a day or a year. If the metric system is entirely superior, why don’t you demand we all switch to metric time? A year will still be roughly 365 days (again, setting aside the inaccuracy) but we could divide the day into 10 equal metric hours, or mours, and those mours into 100 metric minutes, or metrinutes, and then those metrinutes into 100 metric seconds, or meconds. 1 mecond would be 0.864 seconds, and a metrinute would be 1.44 minutes, which to most people would be an imperceptible difference in time. Hey, how many seconds is 1.44 minutes? You don’t know without a calculator because we don’t use metric for time, and it probably never bothered you once before now. What an insane, non-logical unit of measure time is.

      Yes, metric let’s us convert millimeters to kilometers, or helps us determine how many calories it take increase 1 cubic centimeter of water by 10 degrees kelvin. It helps with those things because the units are arbitrarily defined to make the math easier, not to make the measurement easier. But that’s it, there’s no additional sanity, no additional logic. It’s easier to convert between units via math, because it was designed to be easier to convert between units via math. There are no additional benefits to the metric system.

        A foot is a foot. Fantastic. Glad to know everyone has the same sized feet.

        And the same length on their legs so we all pace the same distance.

        I would say good troll, but it just seems too long to be ironic.

          There aren’t many instances in normal life where accuracy and precision are that important. Modern humans can measure distances with lasers and satellite coordinates. You probably own a tape measure and at least one type of scale. But unless you’re building something, baking something, or selling something by weight, estimates are almost as good as knowing something precisely.

          We see the same in countries that us metric. Most people estimate how many meters, kgs, or liters things are because taking the time to accurately measure isn’t necessary. Maybe your phone tracks your daily jog, but that’s only going to be accurate to within a few meters, and most people would round off to the nearest significant digit anyway.

            Yeah, because building, baking, or selling something by weight are totally not important and absolutely common “instances in normal life” 🤡

            Good fucking grief…

              Correct, the vast majority of humans won’t build, bake, or sell anything that requires scalable units of measure. A cup of milk doesn’t need to be precisely 237 mL of milk, nor would most people need to scale their recipe to feed 1,000. If you’re building a shed, dimensional lumber is plenty precise, and it doesn’t require converting the height of a ceiling into miles.

                Jesus wept 🤦‍♀️

                You do understand that precision has absolutely NOTHING, at all, to do with the units you’re using? Right?

                And yes, when you’re baking, you need precision. Try making consistently good bread just by rule of thumb, I’ll wait for your results.

                BTW, measuring things by weight is not just more precise by far, most of the time it’s also easier and faster.

                But hey, be my guest trying to gauge that cup on your beaker that’s 10% off.

                And yes, if your butcher sells you meat, you would like to pay what you bought, and not 5% more.

                And it doesn’t matter if that’s g, lbs, oompah loompahs or whatever. 5% of something is 5%.

                FFS is this a knuckle-dragging contest here?

                  For someone so belligerent about something so inconsequential, you’re also entirely wrong about almost everything. Ice your britches.

                  You do understand that precision has absolutely NOTHING, at all, to do with the units you’re using? Right?

                  Baldercrap. One of the primary advantages of the metric system is that it can scale down for additional precision as necessary. Metric easily scales infinitely in both directions, so you only need one unit of measure for each type of measurement. Imperial units don’t easily scale, so the level of precision is tightly bound to the unit you select. You’re not going to get the same precision from miles that I will from inches. So that was a stupid thing to say angrily.

                  And yes, when you’re baking, you need precision. Try making consistently good bread just by rule of thumb, I’ll wait for your results.

                  Yeah, that’s why I brought up baking as an example. But the cool thing about baking is that recipes exist in both metric and imperial units. I can measure my flour in ounces if I want, and take a teaspoon of salt, half a cup of milk, one large egg, and there’s never any reason to convert between those units because who cares? I’m not making dough for 1,000 loaves, nor would I ever need to figure one one-thousanth of a loaf, so metric doesn’t provide any advantages for the typical home baker.

                  BTW, measuring things by weight is not just more precise by far, most of the time it’s also easier and faster.

                  With a digital scale, sure. I have one and it’s great. I highly recommend it especially for baking. But digital scales weren’t always widely available or inexpensive, and most people don’t own one. Nearly everyone who uses a kitchen to cook will have access to measuring scoops. And not for nothing, but my grandma never measured anything and was an excellent baker. It took years of trial and error but she could adjust her recipes to a humid day to make perfect baked goods.

                  And yes, if your butcher sells you meat, you would like to pay what you bought, and not 5% more.

                  And it doesn’t matter if that’s g, lbs, oompah loompahs or whatever. 5% of something is 5%.

                  That’s why butchers use scales. Grocery stores also use scales for produce and deli produces like cheese. Would it surprise you to learn that the vast majority of humans in America are not butchers or grocers? Their math might be easier with metric, especially when ordering bulk quantities, but for the typical customer, they want an 8 oz steak and a half pound of cheese. So why don’t butchers and grocers use metric?

                  Because their customers don’t use metric, and there are more customers than butchers or grocers. The conversion between units of measure, the entire reason metric exists, just isn’t a daily consideration. It makes no difference if the steak and the cheese weigh the same, or if you can scale up and down.

                  Also, another tangential point, most of the math today is handled by computers. Figuring the unit price of a side of beef or a pallet of cheese isn’t something people need to do in their head anymore. The inventory database will effortlessly convert between pounds and ounces and stones and tons. It can even convert everything to metric if you like.

                  FFS is this a knuckle-dragging contest here?

                  Gosh, you’re rude. Maybe spend less time attacking me personally and try to think of a valid argument. Or better yet, just go back and actually comprehend what I wrote, and maybe you’ll understand that our positions aren’t really that far apart.

                    You can take any unit and break it down or scale it as much as you like. You can have a milli-inch if you want do, it’s 1/1000th of an inch.

                    Now get lost.

                  precision has absolutely NOTHING, at all, to do with the units you’re using

                  1 degree Fahrenheit contains the same amount of heat as 1.8 degrees Celsius. The base unit provides more definition. If you’re limited to just whole numbers, Fahrenheit will give you more precise information about heat.

                  Of course, decimals exist, so it really isn’t a big deal.

                    It’s not a big deal, it’s patently false. Unless you deal with some fundamental limit, like the Planck constant, you can split any unit as much as you like.

                    But at least you admit you just make up baseless „arguments“ simply in order to be right.

            Yes. People estimate things. Because we don’t carry around a scale in our pockets. What does that have to do with anything?

            The point of metric system is that things should be scaleable. And relatable. Between different types of measurements, such as weight and volume.

              Yes, that’s the point. The imperial system has been succesful and remains popular because people do carry around (rough) scales with us most of the time, and because the advantage of being accurate and scalable really isn’t that useful in day to day living. Having a single unit of measure for the length of a aheet of paper and the distance to the nearest city isn’t a significant advantage for most people in most applications. I don’t need to know how many inches are in a mile, because the conversion usually isn’t necessary. The point of the metric system you’ve described has no advantage in most normal use cases, and we use it when it does have an advantage.

                What do you mean “remain popular”? The imperial system has roughly 500 million users. While metric has over 7 billion.

                And even in the countries where imperial is used, the scientific community in them still use metric.

                How can you even attempt to talk about the advantage of normal use, when you don’t even know how to use them?

                Metric is a tool. Just because you don’t know how to use the tool, doesn’t mean it’s not advantageous.

                Ofc conversions in imperial isn’t necessary, it’s gibberish. No normal person will be able to relate the two.

                Your argument boils down to you telling us writing is pointless because no one knows how to read.

                Ofc they can’t read when there’s nothing to read.

        Every imperial unit of measure can be estimated whilst naked (but preferably clothed).

        so I can ask a 9 yr old child to walk out naked to the streets to measure a thing in their foot and:

        • I’ll get the exact same answer as if I send an adult priest naked to the street to measure the same thing in their foot
        • I’ll not get the priest to rape the kid

        ?
