You do know that whensomething is needed in greater accuracy than a tenth of a millimeter, you just go down to micro or nano meters? you can also make just as accurate fractions of metric measurements, it's just that there are prefixes for smaller increments that is used instead of fractions.
And the only reason Fahrenheit makes more sense to you as a ambient air temperature scale, is because you are used to it.
It's equally easy for someone used to celcius to know that 25c is nice and 38 is to damn hot, as it is for you with 77 and 100
I’m sure you can but can you find tools that can measure and cut that accurately, that don’t cost a fortune. You can use a ruler and a pencil and get to a 1/64 of an inch accurately. There’s a small chance you could make a ruler in micrometers and be able to read it with any sort of accuracy, nanometers forget about it. You would really need calipers, and then ones that measure over a ft, 30.48 cm would be extremely expensive. I know the digital calipers that are 8” cost about $200-$300. Yet you can get a yardstick or a tape measure that is much much cheaper and have it graduated out to 64ths of an inch and make more accurate measurements and cuts. When I spoke to coworkers who did woodworking as a hobby in a metric country, they preferred to use English units for measurement.
If and/or when you cook and follow recipes, do you use a graduated cylinder to measure ingredients or do you use teaspoons, tablespoon and cups (and fractions of those)? I just looked it up, there’s actually a metric teaspoon 5ml, looks like you guys are coming back to English units as well. Lmao.
And trust me I get the whole, I’m used to this measurement system, I’ve worked in foreign countries (as an engineer) that mandated metric/Celsius. Some of them I’m like ok whatever, just multiply by 3.2 x meters to get ft. Or kg to lbs just multiply by 2.2. But when I’m told the outer diameter of the pipe is 177.8 mm, that literally means nothing to me, just have me put in my reports 7”. Or densities in kg/m3, vs specific gravity units or lbs/gal for fluids. So I’ve had my bones to pick on this for awhile.
