    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.

      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.

            Are you under the impression that Americans don’t know how to use the metric system? We learn to use it in elementary school. We regularly go between the two and relate them to each other.

            Your comment is unnecessarily arrogant based on complete ignorance.

              No. It’s based on my own experiences from living in the US. I had the wonderful luck of meeting a woman i love. She happened to be an American. So I would like to think I’ve spent a fair amount of time interacting with Americans from many different walks of life.

              They know it exists. But they do not know how to use it. Because they are not taught how to use it.

              I’m not insulting Americans for not knowing something they were not taught. But I will ridicule you for trying to argue against something you don’t understand.

              the answer to how much energy you need to heat up 1 liter of water 1 degree C is 1 kilo calorie (1kcal).

              The answer to how much energy you need to heat up 1 gallon of water 1 degree F is go fuck yourself I’m not looking that up.

                You should be able to appreciate that different people have had different experiences, and in a place as large as the US, there are going to be a whole slew of them.

                I personally studied metric in elementary school and middle school. It’s what’s used for science, how could I not have? If others didn’t learn that and instead had everything in imperial, that’s news to me. It’s perfectly possible though, with just how large the US is. It does make me a bit surprised that Missouri of all states taught this, but maybe it was unique to the district.

                  And i studied biology and chemistry. How much of that do you think I remember after 15 years of not having to use any of it in my job?

                  Think we can apply the same logic to other subjects. You learn about Metric. And then you go back to never having to use it because metric just isn’t used in the daily life of the average citizen.

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

        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?

            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.

              You know what that makes you? A fucking troll.

            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.

              To be honest I regularly convert between units. Especially mm, cm and m (sometimes km) and liters to kg. And g and kg. So I dont really understand how that isnt neccessary for the majorjty of America. Does noone build stuff, or I dont know, put a picture up a Wall, stuff like that? I know you said it is easy to half stuff in imperial. I dont really half stuff that often? When measuring stuff I mostly add, subtract etc. I very rarely just take 50% off whatever I measure. What do you do to need so much halfing stuff? If I need rope I want a specific length of rope not half the rope that is on the wall.

              Yeah, I’m not reading your wall of text on „something so inconsequential“, lol. Clown.

              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.
