Military, most manufacturing is metric only thing that’s not metric are street signs, building trades and anything else the redcaps interact with daily.
Our entire company wants metric. The guidance folk want to do their modeling in metric. The prop team wants to do fluid/thermo in metric. The structures team wants to do load analysis in metric.
But the boys at the 'pad are imperial only. The water system, fuel tanks, all ground infra is in imperial. If someone runs down to the hardware store they can easily find a fitting, gasket, or o ring in imperial. But metric? Good luck.
So our company decided to support both. The flight computer and ground software did unit conversions, everything was unit-aware, telemetry was occasionally manually converted because the onscreen wasn’t the right unit. We had written our own turing complete, inhouse programming language and we ended up implementing dual-static typing. We had float, int, bool and then we had units where some operations required the units to be the same thing. So cm and inch but not inch and kilogram.
The project was terribly mismanaged. To this day some still wonder why.

On February 12th, 2023, Redditor thereveldune4 posted an image to /r/blursedimages that showed a bear and a wolf staring at each other, using a Kubrick Stare POV of both. The top photo was captured by Peter A. Dettling. The post received more than 36,800 upvotes in five months (shown below).
Spread The post gained iterations after viral reposts surfaced on Instagram months later. For instance, on June 15th, 2023, Instagram user @huge.poop uploaded the photo, receiving more than 45,000 likes in one month. Then, the image grew popular as an object labeling template. For example, on July 13th, 2023, TikTok user @suj7683 uploaded a photo slideshow of the image comparing requirements of Formula 1 in 2007 and 2023. The post received more than 1 million views in one week (shown below, left). On July 15th, 2023, TikTok[4] user @formula_1_freak uploaded a similar slideshow, comparing Formula 1 and Isle of Man TT. The post received more than 1.8 million views in five days (shown below, right).
Eh, I DEFINITELY don’t care about this enough to make a Reddit account, wait two weeks so I can send a private message, wait an indeterminate amount of time for the guy who posted it to find my message and MAYBE reply (assuming his account isn’t banned, which is unlikely since this is Reddit), or post hundreds of spam comments to get enough karma to meet whatever that sub calls their karma requirements. If no one has the source I guess I’ll just never know.
The original image of a bear and wolf facing off against each other comes from an image originally taken and published by Canadian wildlife photographer Peter Dettling. Dettling even managed to capture the bear and wolf looking around as if to check if anyone had seen them lock eyes. Same source…
There’s nothing nice or consistent about those fractions. A third of one is one of the other, but a third of that is four of the other? Imperial units don’t convert in any meaningful or logical way, you have to memorise the conversions. With the metric system, it’s all tens.
And the fact that there are no usable units smaller than an inch and you have to use fractions should drive any craftsperson up the wall.
I agree there’s nothing consistent, but having 3 as a factor in ratios does make things nicer - it lets you stick with integer numbers for more things. I’m not saying it’s better than metric, but I do think having more small factors in ratios is nicer than having only the factors 5 and 2.
I too think having factors of 3 and 4 would be neat, which just proves we should change our number system to base 12, as somebody else in the thread suggested 😊.
The fractions don’t help me when I go to the grocery store and unit price of one bag of nuts is “per pound” and the unit price of another is “per ounce”. You’d better be good at dividing by 16 in your head if you want to price-compare! And you’d better be good at remembering how many fluid ounces are in a quart when you go to the olive oil aisle (hint: it’s not 16).
Is lemmy big enough that we can rise awareness for a change? Or the other way around, can we use the rallying behind the metric system to make lemmy popular?
I don’t think the majority of Americans have strong feelings about it one way or the other (despite what the internet may say). Honestly it’s just so low on the list of priorities that it doesn’t seem like we’ll ever be in a stable enough place to care about tackling it. Hell we’re still struggling to kill daylight savings time and that would require a fraction of the changes required to adopt metric.
We’re trying, but the Sunshine Protection Act is stuck in congress. They’re tying themselves in knots trying to figure out which time we should settle on. Like, I don’t give a duck, just pick one and move on! Ask the farmers and other outdoor workers what they prefer, the rest of us can deal. They’re concerned about traffic and whatever when we’ve seen that time changes cause lost productivity every single year. So infuriating, can’t help but waste time on the simplest things.
That’s where the social network comes in. Have all farmers in a channel and let them vote.
But let’s not forget powerful people who want sunrise in their breakfast room at a certain time. It’s stupid but those concerns should also be respected, among many others that can be considered when the requirements are collected.
As a European who grew up using only metric I like inches for crafting. It’s a good scale for the things I craft and I prefer fractions over decimals when doing quick math or measurements.
But that doesn’t mean metric shouldn’t be the standard.
My driving instructor told me about a Czech guy who drove to Germany to have fun with his expensive car. He reached well over 300km/h and the local government pressed charges. They claimed that although there is no direct speed limit, drivers are supposed to drive at reasonable speed given all circumstances. But because the man made sure to drive at 4 in the morning on the middle of nowhere all charges where dropped.
330km/h is the sound barrier. Sooo you can legally break the sound barrier on the Autobahn.
This is false. Sound barrier is an aerodynamic effect that affects vehicles at speeds close to the speed of sound in air, which is slightly above 1200 km/h (at sea level, normal temperature and humidity).
In a similar situation, someone drove about 400km/hour (I think) I believe for a video.
Charges were pressed, but because he posted people at bridges and regular intervals to assess and communicate the situation, the judge decided he took reasonable precautions and the charges were dismissed.
From Texas. I’m actually kinda surprised to hear how slow people are driving there. Our perspective is largely that the Autobahn is generally people driving closer to 160km/h.
We have roads here that are limited to 136km/h. So it’s kinda surprising to find out that most Autobahn drivers aren’t breaking that speed.
You just drive at how fast feels safe to you. On an empty Autobahn (or on workdays where traffic is usually faster because people driving at that time are more experienced) they do go 150-200 km/h. (90mph - 125mph) But not in the middle lane on a Sunday afternoon…
I personally feel comfortable up until about 150km/h
Hey, we have strikt rules on a highway! For example if you’re driving slower than everybody else and your IQ is under 70 you are prohibited to drive on the right lane even if it’s empty.
It’s just a pun. They’re both units of mass, hence there would be mass confusion.
It doesn’t work with the pun, but the more confusing part for people would probably be the fact that pounds are used for both mass and force, but in SI, the units are different (kilograms for mass vs newtons for force), though that doesn’t really matter for most people.
Pounds aren’t used for mass. They’re explicitly a measure of weight. It’s just almost always in the context of earth’s gravity so the approximation to mass can easily be made.
That’s incorrect. They are, in engineering contexts, referred to as pounds mass (lbm) or pounds force (lbf) respectively. The US Customary Unit for mass is the pound (lb) (aka pound mass, lbm)
Again, that’s incorrect. Pounds (Lbs) are the US measurement for mass. Feel free to provide a source to the contrary. I specified pounds mass vs pounds force because in an engineering space, it’s worthwhile to be specific, but the Pound (lb) is all that is specified in any documentation as the unit for mass in the US system.
I’m not the same person, but it seems like you’re right. Pound (lb) is a unit for measuring mass. The same is true for kilogram. This actually surprises me to some degree, since it had not been clarified like this to me earlier:
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. Nevertheless, one object will always weigh more than another with less mass if both are subject to the same gravity (i.e. the same gravitational field strength).
…
Because mass and weight are separate quantities, they have different units of measure. In the International System of Units (SI), the kilogram is the basic unit of mass, and the newton is the basic unit of force. The non-SI kilogram-force is also a unit of force typically used in the measure of weight. Similarly, the avoirdupois pound, used in both the Imperial system and U.S. customary units, is a unit of mass, and its related unit of force is the pound-force.
I think we’re probably confused of this because in common usage, we’ll ask “how much does it weigh” and expect to get an answer in the unit of mass instead of force, just because the mass of the object defines the amount of force it will have in some given gravity condition.
I see this meme beaten to death yet most people I know use the metric system, and my US based company and their nationwide conglomerates use the metric system too and have for over twenty years.
The Autobahn has become very tiring to drive on. Most people somehow decided that its easiest to drive in the middle lane at slow(ish) speeds, while the right lane stays empty for long stretches. Since you are not allowed to overtake on the right lane, both the left lane and the middle lane are clogged most of the time, averaging about 100-120 Km/h. If the public transportation was a bit more reliable and cheaper I would sell my car.
The problem is that even in low traffic, there is a truck on the right lane every few meters. Often, after you switch to the right lane, someone decides to drive right next to you, forcing you to brake.
It’s just more comfortable to stay in the middle lane.
Now IMHO the real problem is when trucks are overtaking with 101km/h…
It’s just more comfortable to stay in the middle lane.
It’s stil a dick move if the rightmost lane is free. Then you’re effectively overtaking a phantom car at the exact same velocity (as nobody is allowed to pass right).
I agree but need to have “free” defined. If there’s another truck 100/200m ahead then it’s a pain in the ass because like the other said, others behind you won’t do the same and will do a slight acceleration when you go in the right lane (because free space in front = accelerate hurr durr), preventing you from changing lanes again when you get to the next truck and so you have to brake and hope you get a gap again soon to overtake the truck.
If it’s literally empty as far as the eye can see then yeah, move over!
What makes your right to go fast on the left lane more important than their right to go a reasonable ~120km/h in the middle lane?
Nothing, but that wasn’t the created scenario. If the right lane isn’t free, do stick in the middle lane of course (squishing two vehicles together isn’t gonna make them go faster, usually). The scenario created was talking of an empty right lane, which should only exist on the left side, as we should drive on the right side of the road.
It’s like when a lane closes and people that merge in near the end get blocked for “trying to get ahead”. But the road is closed there, not a kilometre before. They closed it there to maximise multiple lanes as long as possible to limit the bottleneck caused by the lane closure—use it so everyone can get through quicker. It must be painful to see for the people that set it up. Whatever the situation, traffic go faster when maximising available space and lanes.
Truck driver have timelines. It is totally okay, if they need to occupy the middle lane. Sometimes even the left lane. It is more rare then middle lane sitters.
But what is not okay is that the cultural habit of “don’t clog” has forgotten. People are ignorant shits these days when entering cars.
If you decide to travel via 100 kph and do not want to flow with the traffic, then just stick to the right lane and flow with the trucks?! This way you have the most fuel savings as well.
It is totally okay, if they need to occupy the middle lane.
Truck drivers are running a commercial operation, I shouldn’t have to be inconvenienced so they can more easily make money - especially not when that inconvenience is caused by them not following the rules of the road.
Sometimes even the left lane.
This may be illegal, depending on jurisdiction and circumstances.

It is about the person sitting inside the ferry. Once you work together with drivers you will change your attitude torwards them immediately. They working conditions are very difficult. Especially when they are crossing jurisdications/states.
When I am driving I have no problems eith truck drivers. They even help going onto the highway or mention radars.
The people sitting in the middle are the problem. Most of them doesn’t even accelerate passing another middle-lane-sitter.
Im driving for two decades. I did multiple years of disposition. I’m telling you: Middle sitters are the problem and responsible for most crashes on the autobahn.

This is the classic “feel sorry for the waiter working on sub-minimum wage, he’s supposed to be subsidised by tips!” bullshit argument. Yes, truck drivers are a victim of the businesses they work for and aren’t paid well enough. That doesn’t mean that they, as representatives of the business they work for, should get away with doing things that are wrong and inconvenience everyone else. Particularly when it is the business that sets the conditions that push drivers to behave as they do.
The truck driver might not be making much of a profit, for the long hours they work. But the truck is there to make a profit. The majority of everyone else on the road is not driving for work. People driving for work should not inhibit everyone else, who are inherently paying a loss to drive somewhere.
In fact, drivers in general shouldn’t inhibit others. Driving in the outside lane when you’re not overtaking is a shitty move, regardless.
Pay attention, plan well ahead to pull out when you need, accelerate as needed so you don’t hold up anyone when you pull out.
If you’re not willing or able to accelerate, then you shouldn’t pull out. By all means indicate your intention (and do so well in advance), but don’t move over until the lane is clear.
When I am driving I have no problems eith truck drivers. They even help going onto the highway or mention radars.
The people sitting in the middle are the problem.
Yeah, but we’re talking about truck drivers who sit in the middle lane.
It sounds like you’re from somewhere where this isn’t much of a problem. The professional drivers are professional. That’s awesome, but know that it doesn’t hold true everywhere, either across the US or in Europe or elsewhere. It’s not even a national thing, driving habits vary by region.
But yeah, people sitting in the middle is a problem. The bigger problem is that it’s so poorly defined - I was taught “if you’re not overtaking within 10 seconds, you should pull over”. 10 seconds is very conservative, I work to 7 seconds.
10 seconds. If you’re not overtaking anything within 10 seconds, you should pull into the inside lane.
This is what I was taught in advanced driver training. However, in practice I use 7 seconds, because I find 10 seconds a little too far to easily estimate by eye. I end up thinking “is that 10 seconds? I’m not sure, maybe” then by the time I figure out it was more than 10 seconds it is now less than 7.
As trucks are governed to a Vmax of 90 kph, and some even to 85 kph, I would suggest you get your speedometer checked, because it sounds like the advancement, required by law, is too high. It shouldn’t show more than 7% more than your actual speed. Truck speedos are more rigorously controlled and show an average of 2 kph too much at 80 kph, so trucks overtaking at 101 kph is not normally possible - of course, speedo manipulation does occur, but it isn’t so rampant that they all overtake at 101 kph.
The point is they are overtaking just slightly faster.
Trucks also spent long stretches in the same order, sometimes they change things up.
The speeds of trucks are measured on-board by a tachograph, so any big deviation can give them a fine, even if they weren’t caught on the spot.
And that 20 second delay really isn’t gonna impact the trip as a whole. Just rolling with it will make your trip less stressful, and therefore more enjoyable. If you’re late, rushing through traffic isn’t gonna make a significant impact, except on your risk of accidents.
Driving on occassion on the A8 near Stuttgart and can’t confirm it.
Usually trucks are clogging the most right line and overtaking each on the 2nd lane.
Most PKWs drive on the 2nd/3rd lane while the racers and overtakers use the 3rd/4th lane.
Also who cares about overtaking from the right. If you drive 120kph and my lane all drive 130 kph I will naturally overtake you. No need to switch lanes if the lane is free. Just don’t overtake at +30 kph but more at 10 kph in relation to base Autobahn speed.
Yeah trucks across Europe are generally pretty good, primarily because in many countries it’s illegal for them to be in the 3rd lane (except sometimes in heavy slow moving traffic).
Overtaking from the right, or undertaking, is often illegal also, though. So while I agree that it should be ok, strictly speaking it isn’t.
What is legal is to overtake on the outside, move into their lane, then the inside lane, then slow down so they overtake you. Rinse and repeat, count how many donuts you can draw around them before they move over.
The law does account for this: If all lanes are well populated and you find your lane is actually moving faster than the lane to your left, you may pass - not overtake - on the right, as long as you are not more than 20 kph faster than the left lane.
The difference is in passing and overtaking: Passing is merely going faster than the other lane, but staying in your lane afterwards. Overtaking, or to give it its correct name of undertaking, is passing and then changing into the same lane as the passed vehicle.
I dont experience that in the part of Germany where I live but either way, have you seen how they drive in other countries? Thats wild compared to Germany…
Most people somehow decided that its easiest to drive in the middle lane at slow(ish) speeds, while the right lane stays empty for long stretches.
Really? In my experience driving on German roads (primarily down near Munich), lane discipline is exceptionally good. The only times I saw significantly lower driving standards was in rush hour.
Meanwhile, the UK is notorious for people sitting in the middle lane. That used to be the rule, the inside lane was the slow lane, middle for cruising and outside for overtaking, however that was changed in the 60s/70s. It’s recently been made formally illegal, rather than just contrary to the highway code, but even trained police drivers are still guilty of doing it.
In the Netherlands they’re very big on pulling back in. So much so they frequently cut your nose off by pulling in so early.
It’s fun seeing how driving styles vary between different regions and countries.
Yeah, that might be the case. I recently drove to Berchtesgaden and it was better in the south. I live near the Danish border. Haha, people here are a bit laid back.
