No one in the US knows WTF a long and short ton are. A ton is 2k lbs. And most Americans probably don't even know the exact weight of a ton outside of "a shit load."
For the most part, we generally only use pounds, feet, miles. Everything else is a mystery. Even ounces, cups and gallons are some fucking magical mystery. Just follow the recipe.
I switched everything to metric years ago, and have never been happier. It made a huge difference in most of the things I do, having a system that makes internal sense. The only thing I still routinely use standard for is sewing, because it's damn near impossible to find any patterns or things like cutting mats in metric in the right sizes for quilting.
There recently was a discussion on lemmy where several US citizens (one of them allegedly an engineer…) tried to explain to me that metric might be „more precise“ (? 😂) but the imperial system more practical, because „everybody knows what a foot is“. When I asked them to add feet to miles I got shouted at (in CAPS) that noone (ever) does that. 🤷♀️
Lol, that sounds very much “as a black man”
I’ll tell you, most of us in the states would love a total switch to metric. We use it where is matters most, but we also have an aging population raised on lead has fumes that think anything they don’t know is “communism” or “wholeness” or whatever else the propaganda right spews. Those are the assholes that pretty much stop progress on anything.
I’m big into 3D printing, actually got into the same argument with another 3D printing guy…. And I’m like, literally EVERYTHING we do is in metric. The whole damn hobby is metric.
I hate humanity
You mean the „engineer“? Well, what can I say, he was insisting his professor at uni taught him „a true engineer can work with every system“.
I mean yes, but the difference is one engineer is just happily pushing around decimals, the other one goes pale when you ask what 1/5th of a gallon in cubic inches is…
Hehe, yea, I was poking fun at the “engineer”. There was a congressman a while ago that got caught posting right wing stuff on twitter from an alt account “as a black man” (dude was white of course”
Sometimes I like to think about the logistical challenges with a switch to metric. The one that always gives me pause is highway signs. Thinking about the monumental task of replacing every speed sign, distance sign, and mile marker across the country in any timely period makes my head hurt.
It could certainly be done, and is probably easier than I think with all the state DoTs working independently on it especially over time. We have a lot of road with a lot of signs.
I honestly hate that argument. "it would cost so much to change all those signs" is just negative talk for "it would employee a shit ton of people, create a lot of jobs, and be a major infrastructure project that could help our economy.". Honestly, the economic benefit of major infrastructure works is rarely talked about as much as it should be. Mainly, I think, because the people it benefits are the ones actually doing the work. And that's scary to a certain segment of society that would like very much that not to be the case.
I don't think it's a valid argument against metric, just a thought experiment to consider about the time needed to implement. Converting would be a slow process, but I agree it could be an economic boost as swapping things is a largely a manual process
Meant to mention in my first comment, I haven't met many other people who like to randomly imagine the ways major structural changes would take place. Lol.
I like to pick a huge project. Like, say, single payer healthcare, or the nationalization of an industry, and then imagine the individual steps that would need to be taken to get there. Doesn't necessarily have to be a project I'd support, I just have fun imagining the ways it would need to happen.
That's a good point, but we don't have to even fully replace them. I admit I don't know the name of the technology but I see many street signs or construction signs that have basically a printed metal sticker slapped over the old information.
I think the bigger one is the construction industry.
2"x4" studs. 4'x8' plywood. 16" O.C.
Changing to 44x95, 1219x2438, 406 O.C doesn't make a whole lot of sense. We could switch over to the metric equivalents (like 1250x1250 or 600 O.C.), but that would mean switching out machinery and would break a lot of standards.
I say that Metric is like color vision. You can see things in whole new and easier ways. People in USC can't understand what others see and insist things are just fine the way they are. Thus the "no one ever does that", "why would you need to know that", "who cares", etc.
It is true that no one ever does that though. That doesn't mean its not a problem, but I've never seen anyone do it. If you need to do something like that and you have a brain, you use metric. Just because its flawed doesn't mean imperial should be completely abolished though. What needs to stop is people thinking imperial is better than metric somehow. Aside from that, its just a weird flawed measurement system.
We don't use imperial in the US, we use US customary. Some units have different sizes in imperial. For example, a US pint is 16oz and an imperial pint is 20oz.
That's how they get you. They make the beer smaller.
I saw that too, and many of them claimed they learn both Metric and Imperial British systems and convert between them all the time. So this stood out now:
I mean, it's true. Ask an American to visualize an ounce of anything other than drugs, and they probably won't be able to. Ask how many ounces in a gallon, and they'll Google it. Even cups aren't well understood. We can eyeball a mile on the interstate, or tell you how tall someone is, or lift a box and guess it's weight to within 5 pounds. But honestly, that's about it. We just aren't really taught to visualize our weights and measures, it's why newscasters keep saying shit like "8 Olympic swimming pools!" Or "the size of three football fields" because we just don't have a coherent system ingrained in us. That's also, I think, why we're so against metrification. Because weights and measures feel hard, because we're basically only semi-literate in our own mother tongue, so a "foreign language" feels like it'd be this huge undertaking.
This really isn't an American thing - it's just human, we can't really visualize dimensions accurately unless we have a good reference. Some may measure the Olympic swimming pool in feet others in meters, but the effect is the same.
Really? ... Am I super weird then? Because I can visualize volume and distance really well. I just assumed that was being, like, literate in both systems of measure.
Everyone can visualize volume and distance really well in their own head. Doesn't mean they're right. Try it for yourself, maybe you're gifted?
I mean, if you're converting feet to miles, you're doing something weird.
How many 39 ft rails do you need to build a 100 mile railroad?
As an American, I understand that metric is better for a lot of things. It also would cost a metric fuck ton (ha!) of money to switch over, and it just really isn't a priority when things work just fine for us here. It's not like we are constantly running into problems that would be easier to solve by using metric, and the people in the few professions that do run into those problems frequently just use metric.
The original idea behind imperial units is actually quite nice. They used 12 inches in a foot because you could divide it in so many ways without using decimals. You can take 1/2 of it, 1/3, 1/4, and 1/6 without ever needing decimals. It's great for mental math with small numbers. That obviously is no longer the most important thing anymore, as we all have calculators with us at all times, and we deal with much bigger numbers on average than they used 200 years ago.
We all still use 360° in a circle for this exact reason. It can be divided up in 22 different ways (excluding 1 and 360 as factors).
You can measure 1/2, 1/3, or 1/4 of a meter, why wouldn’t you? Also, seriously, those common fractions aren’t that hard in decimal. Everybody knows that 125 g is 1/8 kg.
That’s not the issue. The issue is that it’s not consistent between imperial units, you have a zoo of different subdivisions between units. You have 12 inches in a foot, three foot in a yard etc pp.
The issue is it gets really unwieldy in multiplication, 1 cubic ft is how many cubic inches… 1728, how convenient.
Tell me how much is 1/6 cubic ft in inches? How many cups are that? There goes your mental math.
(It is also a common misconception that imperial is „duodecimal“. It’s not. It’s counting to 12 in decimal. If you had a proper duodecimal system, „12“ * „12“ would make 100 not 144.)
And you also say 180°, 45°, 720°. Not 1/2, 1/8, 2.
Ok, I have heard this argument before.
If you go down this rabbit hole, you will eventually realize that it is our base 10 number system that is weak in terms of divisibility. If we counted in base 12, the metric system would follow suit and you'd have your convenient fractions.
In my "perfect world" musings, however, I jump back and forth between base 12 and some power of 2 base. The latter would not be very naturally divisible but would make basic arithmetic much easier. There is a reason computers prefer binary.
The other point I'd like to raise is that even in the imperial system, you are not spared having to deal with awkward fractions, as you will realize when you walk into a hardware store looking for that 5/64" screw. Apparently, fractions are not a deal breaker in this case, so perhaps we should refer to a third of a metre as simply that: 1/3m?
lbs = elbows? 2 thousand human elbows?!
Yes. Jesus, why can't Europeans educate themselves on real measurements! We measure in feet and bald eagles for distance. We measure in shotgun shells, elbows and pounds for weight. We measure in ATNT for temperature. That's Ambient Truck Nut Temperature, which is the temperature of a pair of truck nuts after driving for 80 bald eagles at 40 bald eagles per Active Shooter Warning, at sea level on a Wednesday. It's not complicated.
it's from the Latin "libra", for balance, like a set of scales. the £ symbol for pounds as in money is a stylised L for the same reason!
etymology lesson over, imperial/customary gtfo resumes. metric ftw.
