Au contraire, the imperial system is more like a litmus test for metric fajitas, and akin to a set of 'limiting clothes' for American scientists which both eliminates the retards trying to get into the field and also forces the scientist to be more dynamic, assertive, and open minded than his europeers which is obvs why America is leading the world in terms of Nobel Prize winnders.

You just tried to prove the metric system superior by proving my suspicion of poor math skills. You converted fractions too decimal then back to fractions, essentially imperial to metric then back to imperial in this case, that is just asinine and asking for errors to creep in. You do not really do math like that, do you? Pick a system and stick to it, if the project is in imperial, you use imperial, if it is in metric, you use metric.

Even the metric system itself acknowledges its own failings, it allows certain non SI units like the degree (angle) because it knows metric just makes some things harder and less intuitive and almost no one pushes for the use of metric time.

That is what I did, had the answer by the time I finished reading the problem.

Breaking measurements up in this way was done for the simplicity it offered in the days before paper/writing were cheap and common, it is also part of why base 12 was the choice, we counted on our fingers. In the simple method our four fingers were divided into three, the knuckles and the thumb was the pointer. In the more complex version you had the knuckles and tip of pinky, ring and middle fingers to get your 12, index was a sort of tally and thumb the pointer, it essentially made the hand into an abacus. For most stuff the left hand would do the math and the right wrote the results, but sometimes both hands were used for the math.

Used to know a fella who knew it well, he was as fast as a calculator and could do fairly complex math using large numbers with ease.

The fact that the unit of measurement that rules the navigation that makes the modern world possible being imperial is not enough? There are plenty of other examples, the degree is just the most common that one is likely to encounter and probably has a larger effect on the world over then the rest combined, it is hard to beat the mighty degree. Other wide spread non-SI units include the au, time, decibels and the ubiquitous litre. Few if any fields/countries are truly metric, they have to allow these non-conforming units just so they can pretend.

Yes time is technically more common than the degree as far as imperial units go, but that is too easy.

The complexities of using the radian are much larger than you pretend, manual navigation is still needed and the math is far simpler and less error prone with degrees/minutes/seconds. The only way radians can be as simple to use here is if we go to metric time and abolish longitude and latituude, otherwise it just complicates the math. Things go wrong and equipment fails, you have to be able to navigate the old way to get a captains license and that will be done with degrees, what it would take to switch would require every clock and chart the world over to be replaced, not going to happen.

The complexity of converting the worlds air traffic to radians is massive.

>Plenty of planes have metric for distances or can be switched between them, if you are in Europe on a plane, the pilot gives the cruising altitude and distance in km not miles when he gives his little speech to the passengers.
I have doubts European ATC uses metric though. All modern planes have primary indications in retarded units, at least I think it is so. And I'm not sure if american or European planes have metric indicators, so pilots probably convert feet to meter.
In Russia only in 2017 they started to transition from superior units (SI) to inferior.

Also, you know what really pisses me off?
Imperial in PCB design in through-hole components, and metric for some SMDs.

Also where we get our 60 seconds and minutes, which combined with that graphic explains much about our navigation system and why it works so well, it is one of those few things who math all comes from the same source/base.

Our 12 hour day and night comes from the Egyptians who also felt it was more important to divide the day and the night equally than it was to have equal hours for day and night. Day was 12 hours long and it lasted from sunrise to sunset, night was 12 hours long and it lasted from sunset to sunrise.

Too my knowledge 60 has no connection with the measuring of distance, just the division of the circle and the clock. The imperial system evolved out what worked best for different fields/trades and the rest was sort of filled in if needed. It works great from the practical sense, since the surveyor and cabinet maker have no real need to exchange measurements, the surveyor will never survey a cabinet size bit of land anymore than cabinet maker will make a cabinet to fit surveyed land. It causes some headaches when you get to the higher math or start building sky scrapers, but works wonderfully on the scale of the average persons life.

>>1683926
It is not, it has multiple bases but we primarily work within base 12 represented by a base 10 numerical system. Base 12 is a subset of 60 and can fake it fairly well, just does not handle the big numbers as elegantly.

Metric system, a made up system not based on anything by smelly french fagnasties who hated the British and their Imperial system of measure, based on real world things.
Not until recently did the metric cock gobbling frenchies try and base things like a kilo on some made up standard, like a 4mmcubed piece of titanium or some shit. A liter on a volume of water of a certain sized container. Other than that, before this standardization, metric base units were defined by like how much jizz you'r ol lady could hold from her pimp was a liter and shit like that. Just because they want to try and make it base 10 to dumb it down for the retardoo french, ching chongs and vodka monkies. You can decimalise and fractionalise metric as well, stupid frenchies.

What was that example above, put it in metric.

2m,5-3/16mm + 6m, 2-7/8mm.

Eh, anything can be subdivided and fractionalised and decimalized.

Australian here.

I used to be of the same, reddit /r/science etc tier opinion that the metric system makes perfect sense.

But after politically maturing past the lefty default we're brought up in (I do think it is relevant to politicise this), I realised that the metric system is as arbitrary as dividing France into squares.
>all the departments are equal!
and yet totally arbitrary.

The metric system might have 'equal' measurements, but its the basis for most of those is still arbitrary.
The Imperial system may be harder to divide, but the units are relevant to Man - they are relateable, human, and intuitive for day-to-day use.

Plenty of people did not, as I said, 16 and 10 were both fairly common as well, but my question had nothing to do with what ancient people used, it was, why did the largely base 12 imperial system go with a base 10 number system. Don't see why this is so difficult to grasp, it is a simple enough question and has nothing to do with fixating on anything.

>>1684165
>Phoenecians
And they got it from the Sumerians. Sumer is 6500BC to around 1940BC, technically later, but the empire was more or less dead, everyone was leaving the area for greener pastures. Phoenicia is 1500BC to 300BC, and also sort of piddled out slowly after the empire died.

Metric system is based on strictly scientific definitions and is very logical, but I still put one tea spoon instead of 0.1 cubic centimeters of pepper into my cup noodles. Metric is good for whenever you need accurate measurements but in everyday usage you can measure things by the hogshead or whatever silly unit like that.

the fake and gay system is actually metric. Imperial is the old egyptian system and actually conforms to how things are laid out in the physical world. It's intuitive because its units are universal law. Metric is a perversion trying to obscure this law. this was understood in the past but the knowledge has faded away from the masses.

Back then they used decimal numbers, and it wasn't largely base 12 either.
>The Roman foot (~296 mm) was divided into both 12 unciae (inches) (~24.7 mm) and 16 digits (~18.5 mm). The Romans also introduced the mille passus (1000 paces) or double steps, the pace being equal to five Roman feet (~1480 mm). The Roman mile of 5000 feet (1480 m) was introduced into England during the occupation. Queen Elizabeth I (reigned from 1558 to 1603) changed, by statute, the mile to 5280 feet (~1609 m) or 8 furlongs, a furlong being 40 rod (unit)s (~201 m) of 5.5 yards (~5.03 m) each.

>it probably has more sense to use nautical miles, because they are somewhat equal to a minute of latitude degree I think
A minute is exactly 1/60 of 1 degree, which is 1/360 of a greatcircle or meridian. A minute is defined as 1852 meter or 1 nautical mile. Proportional to the size of the Earth, just like the French originally defined the meter (I believe it was a fraction of the meridian that crosses Paris).
I don't know why some anons above are calling the nautical mile an Imperial unit.

I think you mean to say that at the equator 1 minute has a length of 1852 meters, which is 1 nautical mile. At a distance of say, 100 meters, 1 minute would be considerably shorter.

what 5/16 bolt has a 22mm(or 7/8'') head, also that pitch is p easy to convert, its probably like 1.0xmm (24 tpi). but imperial bolts suffer from other deficiencies not related to unit preference, such as nominal diameter to cap/head diameter ratio, a smaller root to nominal ratio, the fact that several standard thread sizes close in diameter use the same pitch (6-32, 8-32, 10-32), the fact that they stop using fractional values below 1/4 and start using numbers with a formula (.100'' + (N x.013) or some bullshit to find the nom diameter of say a 6-32 bolt, where N is 6), the fact that using an imperial allenkey 1 size smaller will strip the hex (in metric the 1 size down will not engage the hex)

I'm an American engineering student, so I have to use both as part of my classes. I prefer using metric to do calculations, mostly because it seems to simplify dimensional analysis. Though maybe I'm biased because of being a physics major before switching, where we worked exclusively in metric. I still use imperial in my day to day life, or when I have to for a project.

There was a time when all the worlds international treaties were written in french, and france was the center of the world culturally and in other ways.

Today English is the international language, and is the center of the world culturally, and in other ways.

140 years from now, the USA will be just the same way, and everyone will complain about vacations here because US Citizens are rude to travelers and think they are better than everyone else. There are lots of terror attacks from the white nationalists ( not to mention the city sized ghettos ), and the people refuse to speak anything other than English much less Chinese, the current international language. China owns significant portions of US real estate, and even purchased Alaska and Puerto Rico. They took that whole debt default pretty seriously, froze the US out of international trade and basically starved it into submission. 140 years of climate change had done the rest. Once the multi-nationals had completely relocated, the US was just another shitty post-environmental collapse 2nd world country.

Like most units of measure, the units of the metric system were based on perceptual quantities of the natural world. But they also had definitions in terms of stable relationships in that world: a metre was defined not by the span of a man's arms like a toise, but on a quantitative measure of the earth

Thats a question I never ask myself. Where I live only metric is used and thats fine for diy.
The outcome of the project wont be determined by the measurement system used, as long as the user knows how to use it. Looking at the industries in the USA and in Europe, both can produce outstanding products of high precision, one with the meric and one with the imperial system respectively.
Now for diy I would say use the one you feel the most comfortable with, as stated above, everything is possible with both systems as it is done so in the respective contries/industries.

Some math is simpler with imperial units in some cases. If you argument is that it's generally simpler to convert between units within metric, then I'd agree with you. As it stands your statement isn't entirely true as it's subjective and variable. I get that it's a small nitpick but I think it's necessary.


For the record I usually recommend people learn both if they can and learn to convert between them. It's really not particularly hard and if nothing else it's a nice mental exercise. Don't be a mindless slave to just one number system if you can help it.

adding fractions is easy as fuck, and it was one of the main reasons people worked with them instead of decimals before everyone carried around calculators in their pocket.

Once you become even halfway proficient at it(which should take like an afternoon at most) it's way faster to add fractions in your head than it does punching decimals into a calculator. The majority of the few operations you have to carry out are simple additions and subtractions.

Plus halving, quartering, eighthing, sixteenthing something or doubling(reversing) something is also simple as balls.

I purely use metric due to being an eurofag. In my old job I had to deal with some amerifag equipment, which of course required me to use imperial.
As a result I have equally exposure to both, so I would say that whichever you're used to works. Some find the fractional noture of imperial a tad unintuitive if they're used to metric, that's about it.
