Who the fuck ever uses the candela?

>>212172916
I do

>>212173008
What for? Declare your intentions.

yeah it's kinda gay how you guys use a weight system to calculate mass because you can't get your own heads around newtons. guess that reminds you too much of fig newtons? in any case it doesn't matter to me cuz yer all poor lololol

We learn imperial in elementary school and then swap to metric

>>212175575
imagine if you learned metric in elementary school and didn't have to bother with imperial at alll, thats the rest of the world for you

>>212175521
>you can't get your own heads around newtons
1 newton is a force required to accelerate 1 kg of mass at 1 m/s^2. Mind telling me what’s a pound-force?

>>212175699
I learned both metric and imperial in elementary school.

People just don't know metric as well because they don't regularly use it colloquially. To be fair, I don't think people really know imperial that well either, how well can people actually perceive what '15 feet' is? USA uses metric in many official circumstances, its incorrect to state that USA does not use the metric system.

>>212176056
>how well can people actually perceive what '15 feet' is?
It’s 1/24th of a football field or about 6 washing machines.

Euros can't even do the conversion from football fields to mcdoubles in their heads

>>212176056
there's really no excuse why you haven't switched yet, all other countries managed to do it and the people were also opposed to it, it's one of these things the government has to do because the majority of people are just retarded and will do anything to stop progress

>>212176222
>progress is uhhhh measurement units
What?

>>212175699
Imperial today, imperial tomorrow, imperial forever.

>>212176302
standardization of measurments is progress, yes
>>212176345
backwards today, backwards tomorrow, backwards forever, what a great mindset

why do we use hours, days, weeks, and months
as a true SIGOD, i insist on using kiloseconds

>>212175699
Imperial is based, you fool
Also ours is actually called US Customary, Imperial is the British system with stones for measuring weight

>>212176411
What the fuck is progress to you? Some nebulous utopia like “communism” was for Bolsheviks? Literal brain parasitism.

>>212176448
The French had a “metric calendar” but abandoned it.

SI units are just as arbitrary as imperial and worse because the range is dumb, 0-100 for water is irrelevant to people, Fahrenheit is superior and gives better resolution per degree

>>212176464
I believe humans are better organized collectivist than individualist so a collectivist ideology is progress compared to an individualist one, yes.

>>212176555
Of course they are just as arbitrary. Imperial units are defined via metric. An inch is 2.54cm. No other definition exists.
>muh 0-100
Kelvin is defined via the Boltzmann constant, not water.

>>212176621
>Kelvin is defined via the Boltzmann constant, not water.
cope, ther'es reason water boils at 100, because it was chosen for that
>b-but later we refined it
nobody cares, your unit is worse.

>>212176637
you can't even go to the moon much less mars lmao

>>212176685
Water doesn’t boil at 100. There’s no fixed temperature for water to boil at all conditions. Learn basic physics.

>>212176555
>the freezing and boiling temperature for water is irrelevant for people
water is literally the most important thing for human existence, it is vitally important and having its freezing and boiling temperature fixed to 0 and 100 is pretty neat, also if you want greater resolution you can use fractions of degrees but in practice only .5C is used and even then I don't think humans could reliably tell .5C difference if it were tested in a scientific experiment

>>212176685
>Gets confused by "military time"

>>212176730
you measure air temperature 100x more often than you measure "how close is this water to boiling" you stupid fuck

>>212176742

>achtuakllly it boils at 99.978C not 100.00000000000C so you're wrong
why are germans like this? i'm glad all those bad things happened to your country

itt : sunk cost cucks trying to defend their inferior units. Fahrenheit is superior for human temperature which is what temperature is used for 99.99% of the time

>>212176724
>Dosn't know how to fight in proper order, gets a prussian to teach you. Doesn't know shit about cars, gets a german to build them. Doesn't know shit about rocketry, gets a german to build them.

I see a constant. Memes aside, I like how adaptable you are. Even the whole Auftragstaktik adoption. How many countries are able to change that hard in such a short time?

>>212176883
Because if you want things to be well-defined, then you better make sure you have a good definition. It’s basic physics. Saying
>dude 0F is like really cold
isn’t well-defined.
>i'm glad all those bad things happened to your country
Imagine taking this personally lmao

we all know that germans and austrians got cucked out of being able to be proud nationalists so hard they now resort to pride by being good globalists (most of them are cucks who don't eat meat because it's le bad after being a proud nation of carnivores), but kek this even extends to units

i pity you
goodbye

>>212176662
economies of scale but on human brain. Capitalism. you are dumb

>>212177082
I thought you were shitposting, I hope you didn't mean all this. In any case, good luck.

>>212176724
NASA uses metric idiot

>>212177170
1. They didn’t during the Apollo program.
2. Their contractors didn’t until 1999 when the retards crashed a probe into Mars because they had to constantly convert between metric and imperial and lost track.

>>212176932
>Fahrenheit is superior for human temperature
Why? Substantiate your claim

>>212177242
because the mutt’s used to it. That’s it. Their entire “logic” is
>0F is like really cold dude
>100F is like really hot dude

I WORK IN DIMENSIONAL METROLOGY AND NONE OF IT MAKES SENSE AT A CERTAIN POINT LOL

>>212177290
based NIST employee

>>212177235
yeah I know the point being that even the people who flew to the moon and now are trying to fly to mars have to use metric as it is more reliable. Also iirc they used both systems interchangeably beforehand

>>212175699
When are we moving to metric time? Imperial time is retarded and inelegant
>60 seconds to a minute when it could be 100 millions to a centisol
>60 minutes to an hour when it could be 100 centisols to a decisol
>24 hours to a day when it could be 10 decisols to a sol
>365 days to a year when it could be 1,000 sold to a kilasol

>>212177411
Second is already metric, Nigel. It would be milliseconds (huh), kiloseconds, etc.

>>212177411
>millions
millisol

So 1 litre or 1000 cubic centimetres of water weigh exactly 1 kilogram at room temperature.

How's a "pound" defined?

>>212176411
We need to standardise languages too. It's backwards to cling to your own native language

>>212177500
A pound is exactly 0.45359237kg. That’s the official definition, not kidding.
Oh and a kilogram isn’t defined via water, but via the Planck constant.

>>212177518
standardize* your own language's spelling first bong

>>212177411
I think that the hours are alright since they correspond to 360° which is used on clocks. We do have to switch to either lunar calendar or metric time though. Also time should be counter YYYY/MM/DD/HH/MM/SS

>>212177634
>lunar calendar
Ahmed, please.

>>212177557
I know it's not defined that way now, but it started out as the weight of one litre of water. Same as the meter started out as one ten-millionth of the distance between the north pole and the equator. Today it's defined in terms of what distance light travels in vacuum in a defined fraction of a second.

>>212177443
I'm basing it off of day length, Fritz.

>>212177634
*on clocks
*switch to lunar when it comes to months

>>212177705
Mass, not weight :)

>>212175988
Bodied that fat and dumb freak

>>212177634
>360°
Shouldn't that be 1,000 or 100? So much more elegant

>>212177715
What day? Sidereal? Solar? You do know the difference, don’t you? And you do know that these aren’t constant and change due to orbital perturbation, mostly due to Jupiter, right? Sounds like a shit unit desu.

>>212176934
>Doesn't know shit about cars, gets a german to build them.
Henry Ford was Irish.
>Doesn't know shit about rocketry, gets a german to build them.
Robert H. Goddard was English.

>>212177741
Leave this planet. Otherwise you won't have a reason to differentiate between mass and weight.

>>212177682
The Chinese also used lunar too and I think that that makes more sense than having months of uneven sizes, without an logical order that were created only because some Roman emperors wanted their name in the calendar

>>212177861
Acceleration due to Earth's gravity isn't uniform, anon. The Earth isn't a perfect sphere.

>>212177779
Idk it would be kinda annoying in math but we can do that. now that I think about it maybe we could create sexagesimal metric

>>212177904
negligible.

>>212178049
>can be measured
>negligible
That's not how you establish a robust measurement system.

>just outright ignoring stuff
poland pls these differences in gravity can matter!!

>>212176222
We already have switched in many ways.

Things we use metric in:
-nutrition
-liquor, wine
-science
-drugs
-pharmaceuticals
-military
-Track and field
-Electricity
-Photography
-Fertilizers
-Jewelry

Things we use imperial in:
-Gas
-Human height/weight
-Weather
-Construction
-Transportation (road signs, speed)
-Aviation
-Beer
-Agriculture
-Real estate
-Team sports (though soccer is Imperial world wide)

Mixed/both:
-Food packaging
-Manufacturing
-Education

What specifically do you believe the USA should switch to metric in? Keep in mind most of this is either expensive to switch (construction), or impossible for the government to do (human height/weight).

>>212178290
Yes, they matter when you make very precise force measurements, for example the Casimir effect. So if you base your unit of force on "Earth's gravity" (ahem pound-force ahem) suddenly people will measure very different results for the Casmir force depending on where they measured it.
https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.120.040401

>>212178094
I agree but definitions based on plank and shit are only used when you do very specific science or have to calibrate clocks to account for gravity. For an average Joe it is more convenient to use simplified placeholder definition while keeping in mind that they're a little bit off since ultimately both them and real ones exist for human convenience

Why do people get so worked up about measurement systems in an age where it takes 5 seconds to do a conversion using your phone?

>>212178794
desu (reduced) Planck units is all we need
c=h/2pi=epsilon_0=k_B=8pi*G=1
Alas, the common man is not ready for such based units.

>>212178851
You know how long it takes me to convert from meters to centimeters? About half a second and no phone needed.

The only true constant in the universe is the speed of light.

>>212178399
I don't know what that paper is about anon. Before they were doing sphere-plane measurements but they found a way to do sphere-sphere with hollow gold-plated balls in the air. The difficulty is holding things parallel and how to fabricate stuff out of different material? idfk

>>212178966
My point is that it's a very feeble force, so having a precise definition of what the fuck is a unit of force is crucial for unambiguous measurements in this case.
>>212178960
See >>212178873. Plenty of 'em.

>>212179013
and why do we need such unambiguous measurements? we have everything we need atm. the stuff we need to solve lies within ourselves :)

>>212178398
why don't you switch one at a time then, start with something small like beer, since you already measuure wine by the liter it surely won't be such a big deal switching all other alcoholic beverages, then you go from there and do one every couple years, in a couple decades the country would be fully metric, if you had started in the 70s like australia you would be fully metric by now
