For science? Metric is fantastic. For literally everything else - us customary is faster, easier, more understandable, and actually more approachable in terms of trying to actually build something.
Americans keep saying this shit as if the vast majority of the world doesn’t use grams for baking, celcius for temps, and cm for height daily - nobody is imposing anything on you guys, but you are going to continue to be ridiculed for using the dumbest measurement system. Yes, some systems absolutely make more sense than others - having even division of all orders of magnitude is a good example of that.
One could easily spend more time trying to measure 1.905 cm vs very quickly dividing 1 into 3/4". This is purely a skill issue. You’re also clearly being biased by picking a rounded imperial fraction as the basis of comparison, and complaining the metric equivalent is unwieldy. (50mm is 1.968504 inches - oh wow! oh no! how will anybody figure it out?) Of course they don’t neatly line up, they’re not meant to - it doesn’t make working in metric harder because I’m not using both systems? If I need hardware, I have M3 through to M8 for normal screws, bolts, washers, etc. - trying to use imperial is a clusterfuck - they don’t even use the same fucking denominator, thread pitch is not standardised, nothing makes sense, it’s a garbage system.
How many inches in a foot? thats easy - how many feet in a yard?..uh okay a little weirder, yards to a furlong? the fuck - furlongs to fathoms to miles to -… its inconsistent unpredictable garbage because it’s not in any way related to the units above or below it. That’s all WITHIN DISTANCE - good fucking luck if you want to convert that to volume or energy or anything else. mm > cm > m > km - all base 10. Predictable, consistently divisible.
There is no persecution here - you can use fucking apples to measure distance if you like - but please stop portraying SI units as this scientific conundrum which is incompatible with daily life or professional ease. Imperial isn’t actually any easier, americans are just familiar with it All but 2 countries in the entire world have switched over because the benefits self-evidently outweigh the costs…america acts like using dumb dumb units is a patriotic holdout but it is such an ongoing own-goal.
you’re not hearing me - Its fine - please stop trying to convince me how difficult millimetres are, I went to school, I use them with no difficulty It’s really not rocket science to say ‘1.75m’ - we’re all surviving just fine. (Believe it or not, there are even craftsmen using millimetres! 😱) Base 12 is lovely, it’s very cute that you can say ‘3/8ths of an inch’ but it isn’t some universal human truth that fractions are easier than decimals - wait till you see that you can express inch subdivisions as decimals, and metric subdivisions as fractions!
SI is more logical in paper, it is also still more logical in practice. A base 10 unit I have never heard of before intuitively tells me what it measures and how big it is by the word alone. “Decilitres” is not really used outside of europe, but I immediately know it’s volumetric and 10x the scale of litres. Inherently logical. How many fluid ounces are in a liquid gallon? The answer is ‘good fucking luck’ or ‘12 is easy to subdivide by, but now I have to remember every single measurement relation by writ’
The ‘S’ in ‘SI’ literally is the standard measurement system. It is the only universal and internationally standardised system. US feet are slightly different to UK feet, and Australian tablespoons were different to german ones - and if you think SI was dreamt up by a bunch of rich French people, firstly, that’s a bit disingenuous - not how that happened at all, but secondly, you’re going to absolutely lose your shit when you find out the basis of the ‘foot’ (it was the kings fucking foot, a super standardised unit of measurement)
As I said before, I’m not forcing you to use the dreaded centimetre - but please stop advocating against SI units because of hOw hArD tHeY aRe - it’s fine, complete idiots use kms without issue, we’re all gonna survive without reverting to fucking cubits.
