Actual poster from 1917 that made me laugh. A lot.

Also, those motherfuckers are measuring the weight of those balls in kilograms, aren’t they?

    This is among the dumbest internet arguments ever.

    G20/G21. The machines don’t care, my digital calipers, micrometers, rulers, and 3D CAD software don’t care which system is being used. So why should I have my undies in a bunch about which is better? I use the measurement system best suited for the task at hand - whether that’s metric, US customary, or light years.

    As for not knowing how many inches are in a mile, that’s about the stupidest internet point ever. No one cares about that, well maybe some civil engineer might need to very rarely care in some unusual situation. The scale of measurement is wrong for inches. In fact, most people don’t care much about the actual distance away something is, they mostly care about how long does it take to get there. The odds are pretty good you have no idea how far it is from your front door to the grocery store in miles or kilometers. But you DO know how long it takes to get there. Whether by foot, bike, bus, or car.

      Weird how you think inches are only used for long distances and not, for example, making sure a beam is the right length while you’re building a house, or making sure a screw is the right size.

      But I do agree that inches are not practical for long distances. That’s probably why people in the U.S. use miles.

        Millimeter are not practical for measuring long distances either. And measuring the length of a piece of lumber isn’t a “long distance” either

          That is why kilometers are used for long distances in metric. I’m really not sure why you don’t know about how people measure long distances.

            I do and perhaps more than you. I don’t know why you brought your point about inches and scale when I had already pointed out that those who think it’s such a “gotcha” argument are wrong and why.

            Again, use the measurement system and units best suited to the task at hand. And never forget, every measurement system is just a bunch of made up units by some random dude and then modified by some other random dudes at random times.

        That’s people making the dumb mistake of using the wrong units. They could have just as easily used the wrong metric units.

        I’ve designed and built those machines. We don’t care. Pick the proper units for the job and go at it.

            Oddly enough I have helped build a couple of items that flew on the space shuttle back in the day. Which is more than you can say. But most of my work involved industrial machines for manufacturing lines and associated custom tooling. I have machines all over the planet.

              OK. So on projects with international teams you always picked metric?

              What are the circumstances that would give imperial units an advantage?

                You make projects to the buyers specs. But I have made US Customary machines and parts as requested by companies in India, Pakistan, and Great Britain if I remember correctly, (I’ve been out of the business for a good while and I’m now retired altogether). I can’t remember anything in Germany or Japan. The Chinese were always whatever dope dreams they were on that particular day. They could be particularly bad about mixing and matching units for no reason or just making something up out of thin air.

                Let’s see, just off the top of head, US thread patterns are a bit better the the metric ones. While it doesn’t mean as much these days thanks to CNC and G20/G21, (because the machines don’t care). The inch pattern of threads are a little bit stronger, (it’s not a whole lot more), and due to the threads per inch standard, it’s easier to just count the number of threads over a set distance, (1 inch), vs trying to measure a thread crest to crest. This makes identifying threads pitches easier with inch pattern threads when trying to make repair parts. And back when manual machines ruled the shops, inch pattern threads made screw cutting lathes smaller, simpler, and cheaper than metric lathes. You needed fewer gears and shafts, fewer bearings, and less cast iron to make the head stock. This made US lathes faster and cheaper to make and cheaper to buy. Plus you can cut more different thread pitches on an inch pattern lathe vs a metric lathe due to not needing to resort to removing covers of the metric lathe to make gear changes and even swapping to a different threading dial despite the QC gear boxes.

                These small cheap lathes is why, in their own small way, during WW2 the US industrial capabilities grew so fast. Anyone could buy a small lathe for a few hundred dollars, literally carry it up to as second story flat and start making all those small parts for the war effort. Small benchtop lathes were manufactured by the tens of thousands and they were all bought by people, many of whom had little to no experience in manufacturing to start making extra money in their off time from their day jobs. And while many got worn out and scrapped over the years, you can still find those little South Bend, Clausing, and Atlas lathes in hobby workshops in the US today. And they are lovingly used and doted over by their owners.

                US Customary Units are slowly and surely fading into the sunset. And at some point they will just organically fade away, (it’s why there has never been a national law forcing people to switch), as the casual US population just starts using them more and more. We already use the metric system to buy soda and whisk(e)y to searching for that missing 10mm wrench just like every one else on the planet. The only places you still see US Customary units being commonly used is in construction, (inches and feet), travel distances, (miles), and temperature, (Fahrenheit). Construction has backwards compatibility issues making it very difficult to switch from using a 2"x4" to a 50mmx100mm piece of lumber. Not to mention plumbing problems. And distances and speed limits on a road sign don’t really make a lot of difference in how they are shown for the average traveler. And for deciding just how to dress for the weather, what units you are using really doesn’t matter. (Why doesn’t the metric world use Kelvin to measure the temperature in daily use?) It’s not the first time a measurement system has been eclipsed in human history and even the metric system likely will get replaced by something else in the far future. In the end, neither system is head and shoulders better than the other. Nor have I ever claimed such. They both are, after all, just arbitrary units made up by some random dude hundreds of years ago.

                G20/G21…

                  US thread patterns are a bit better the the metric ones

                  Very interesting. Not directly related to measurements but a clear practical reason to chose imperial over metric. Cups are also a more convenient measurement for dry, equally dense ingredients.

                  neither system is head and shoulders better than the other

                  Metric having intersecting definitions (1l of water = 1kg) and being divisible by 10 have clear advantages for mental arithmetic. But if imperial were consistently base 12 I could be convinced to swap.

                  Why doesn’t the metric world use Kelvin to measure the temperature in daily use?

                  It sort of is. At least the scale is the same. Only the base value differs.

                    “A pint’s a pound the world around” is the ditty. Wherever do you think the metric system got the idea for 1l = 1kg? The serial numbers just got filed off that idea and claimed it as if they invented it. If you look closely, there is a shocking number of base ideas of the, “common” usage measurement system, were simply copied and just re scaled and give new names. Since the base values differ, Celsius and kelvin ain’t the same. Not that it matters of everyday usage. I just want to know if it’s going to be cold, nice or hot when I get up in the morning. I don’t worry about what scale I’m using.

                    It’s pretty amazing when you start really looking at things to understand just where something originated from, it becomes apparent that there is very little new under the sun.

          Again, so metric then, as the imperial system is arbitrary shit that make no sense from hundreds of yours ago that only still is in use in the IS and a few third world countries, and ONLY because conservatives in the US refuse to get with the program.

          Literally the entire world switched to the metric system because it works, and the US literally got left behind because conservative values.
