    What I like is the use of parts of inches. Especially the fractions which are powers of two. Very useful. That’s a little difficult with the cm and mm because they’re already so small.

    What? With millimeters you barely have to use fractions because it is so small, how is that a negative? Fractions are also way harder to understand if you need to het precise

      You’ve already gotten two real world uses here.

      I’m not saying millimeters are a negative. Never did I say that. But I will say a base 10 doesn’t have that many prime factors, so using measurement equipment where halves and thirds and smaller marked out can be pretty helpful. Metric measuring stuff never has that.

      I’m just saying that if you are working with some kind of base size, and want to do stuff in fractions or multiple of that base size, the inch is a pretty good size. 👍

      I’m from and in Europe, and I don’t use inches myself. But there are obviously good uses for it.

        I have a hard time understanding why you would prefer that over using decimal places to be honest, adding decimal places together is much simpler than different fractions

          That’s just because you have less practice with the latter. 👍 There are tricks. 😉

      Not flute working but sewing, and I know it sounds insane, but mm is just to small to be practical. It’s one or two strands of tread whereas 1/4 or even 1/8 gives a proper piece to cut of.

      And 1/4 inch seem allowance is just so much less bulky than the standard 0,75 cm, and so much more intuitive for me to work with … and f. I just realized that all my arguments for using inches are based on habits…

      Even though I’m european I never really applied cm in anything but homework and therefore never got a real sense of it. And a lot of the nice sewing patterns are in inches so that’s where i started.

        Well habits are valid and in the end a cm is just as arbitrary as an inch, but converting between units is just objectively easier with metric

      Not gonna lie, if you are working with carpentry or sewing or similar construction or creative work, you probably shouldn’t have any issues with fractions…

        Just try adding 1/3 and 5/8. In my field fractions like that are nowhere near precise enough anyways, so you’d need to work with thousands of inches, which just makes you wish there was a smaller unit like millimeters

          Cherry-picking fractions with prime numbers. 👍 Obviously no harder than using a readily available calculator just like any engineer would with the metric system. That’s fine too. You’d end up with a decimal answer, so then the benefit is lost, just as with fractions of cm.

          In my field

          Yup, say no more. I’m not saying inches are universally better. Only in certain situations.

            I don’t see how cherry picking is an issue when that issue literally can’t happen when you’re working with fractions, I also don’t think those sizes are particularly uncommon?

              Cherry-picking is an issue when you’re trying to make an argument because you’re choosing a very complicated case on purpose when the more common cases are less complicated. That’s gotta be a straw man argument or something similar? I dunno.

              literally can’t happen when you’re working with fractions

              Did you mean to say something other than fractions here? If not, I’m confused.

              don’t think those sizes are particularly uncommon?

              It depends if you are making your own shit or not. You can always decide on other sizes, I guess? But no, they’re not uncommon. But combined, maybe not as common as other combinations? Either way, like I said, the easier cases still make the case for a slightly larger base like the inch. The other cases you can just use cm/mm or a calculator if it’s too much.

              Just to be clear, this has nothing to do with the imperial system itself. It’s only the fact that the inch is a more comfortable size. You could easily just use a base of 2 cm or something and use fractions of that. But common measuring devices rarely mark even fractions of cm. That’s the only issue.

                Ignoring cases where the system brakes down is just as much of a straw man argument, if not more so than giving difficult albeit rare circumstances more attention. In my opinion atleast…

                Did you mean to say something other than fractions here? If not, I’m confused.

                Yeah I meant decimals, sorry.

                I also agree that this isn’t really about metric vs imperial necessarily, although fractions are definitely more commonly used in the imperial system.

                But common measuring devices rarely mark even fractions of cm. That’s the only issue.

                Well then to be even more specific, electronic measuring devices pretty much always mark in decimals anyways, even for imperial. If I take my digital calipers for example, if I set them to inch, they’ll measure with 4 decimal places! Compared to only 2 on mm.

                Arguing that inches are a more comfortable sizes is for one, very field dependent and second, my biggest issue with the entire imperial system; It’s mostly just based on vibes, rather than practical use or precision. We might have a different background but I have a background in design and currently work in the hydraulic sector. And let me tell you, hydraulic fluids at 300 bar (4350 PSI) don’t care whether something was made at exactly 1/4" or not, but they do care when the gap between parts is 0,1 mm (0,004 inch, also known as 4 thou) more or less

                  So is ignoring the cases where it shines, so we’re about “even” there, I’ll “concede”.

                  Arguing that inches are a more comfortable sizes is for one, very field dependent

                  That’s what I’ve been saying this whole time. This whole time.

                  my biggest issue with the entire imperial system; It’s mostly just based on vibes

                  Yeah I’m not arguing for the use of the imperial system here. Only that inches in particular are a nice size for small work but not close-to-microscopic work. And also that fractions are nice when used properly.

                  Other than that, THE METRIC SYSTEM RULES.

                  I hope my point has now fully come across. 👍
