    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.

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

          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…

            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
