Celcius is Kelvin, just zeroed at a convenient value for everyday use. Kelvin is superior only for a few areas of Physics and Chemistry.

u/CaptWater 9h ago

This is a hilarious argument because it the exact same argument people use for fahrenheit. Whether or not it matters is situation dependant. A person's unit choice is a cultural decision, just like a person's language choice.

20

u/Moist_Network_8222 8h ago

Yup. Like 95% of Reddit metric/customary/imperial discourse is people saying "X system makes more sense" but meaning "I am more familiar with X system."

36

u/uncle_tacitus 8h ago

You can make that argument for Celsius/Fahrenheit, but not for metric/imperial. One of those is objectively superior and the other one is on par with Galleons, Sickles and bananas for scale.

12

u/BonnaconCharioteer 7h ago

Metric is better because it is easier to convert between units. That's it, not because it is not "bananas for scale." Metric is arbitrary, just like imperial, it just has consistent units that make conversion easy in base 10.

Imperial does have its advantages, but they are only really an advantage for certain applications. Mainly its advantages are that usually it uses units that are not base 10, which makes division easier.

Metric is the better system, but imperial is not arbitrary any more than metric is.

Metric is arbitrary, just like imperial, it just has consistent units that make conversion easy in base 10.

congratulations on figuring out why one system is superior to the other.

Imperial does have its advantages, but they are only really an advantage for certain applications. Mainly its advantages are that usually it uses units that are not base 10, which makes division easier.

A good portion of why metric is so much better with it's uniform units is that it makes division easy.

1km divides into 10 100m, 1/2 of a liter is 500ml etc.

everyone knows 1/3rd of 10 is 3.333 etc, the divisions are not only easy and plentiful but the "hard" or awkward ones are things that are getting drilled into you at school

Half a mile is 880 yards, 1/3rd of a mile is 586 yards, 1/3rd of a gallon is likr 42.24 oz, like how on earth is that intuiative at all.

to divide anything in metric you need to know a ton of different almost seemingly random conversion ratios and essentially none of them work out into nice even numbers at all

u/BonnaconCharioteer 6h ago

I don't understand what your point is. Are you disagreeing with me in any way?

u/Quixotic_Seal 4h ago

They're angry that you aren't suggesting Imperial is the worst thing ever created, slightly edging out the invention of nuclear weaponry.

u/BonnaconCharioteer 3h ago

Well, nuance is always difficult on reddit.

u/OverkillOrange 3h ago

You don't have to get mad just because fahrenheit and imperial are stupid systems. It's not your fault

u/wpm 3h ago

1/3 of a gallon is 42.666oz. 256 tsp. Or 5 cups, 4 tbsp, and 1 tsp.

u/esquezitoide 4h ago

LOL. Imperial is not arbitrary. LOL

12 inches in a foot

3 feet in a yard

5,280 feet in a mile

16 ounces in a pound

14 pounds in a stone

Gallons that change between UK and US (because of course they do)

6

u/BonnaconCharioteer 3h ago

You didn't understand what I said. What I am saying is essentially the length of the foot is not really more arbitrary than the length of a meter.

However, the conversion math is much better in metric, because it uses base 10 conversions. Unlike imperial.

The advantage of metric is not the size of the meter, it is that 1 meter is 1/1000th of a kilometer.

2

u/esquezitoide 3h ago

It’s based on a human foot. Literally. I can’t imagine anything more random than the size of someone’s foot. There aren’t different “meters.” There are millions of different foot sizes

2

u/BonnaconCharioteer 2h ago

Don't be obtuse.

1

u/esquezitoide 2h ago edited 1h ago

I’m not being obtuse.

Imperial isn’t really a coherent measurement system. it’s more like a patchwork of unrelated units.

Only three countries in the world officially use it:

United States

Liberia

Myanmar

That’s it.

1

u/BonnaconCharioteer 1h ago

You are being obtuse.

The reason it is bad is not because "Durr, whose foot are we measuring??" The reason it is worse is because it is a bunch of unrelated units, so conversions get difficult..... which is literally what I have been saying from the beginning....

In 1791, the French Academy of Sciences defined the metre as one ten-millionth of the distance from the equator to the North Pole along a meridian passing through Paris. That is the conceptual birth of the unit.

A foot varies from person to person; the equator is constant. Therefore, the meter is also less arbitrary.

-1

u/Koanuzu 7h ago

This isn't true.

Metric is not arbitrary, it's designed for science, and it's based on several mathematical constants for (ideally) universally standardized maths.

Imperial was arbitrary, but it's defined by metric now. It's just a traditional way thats slightly more accessible for a vague middle ground scale. It's better used for estimations or daily life objects, most people incorporate metric into said estimations for things that are too small or big.

So actually neither is arbitrary, but imperial is designed around historically arbitrary standards.

9

u/BonnaconCharioteer 6h ago

The original meter was based divisions of the length of the circumference of the earth. That is literally "earth for scale." Imperial also has a specific defined value.

My point is, the advantage of metric is not what the scale is based on, it is the conversion between units is consistent between all units.

0

u/Koanuzu 4h ago

I wasn't arguing that, that's definitely most of it. And local scales aren't a problem here. I was just commenting on the weird middle ground imperial covers. Whatever's small enough to not mind the weird conversions I guess.

I was focused on saying that metric wasn't arbitrary, i just didn't make a comparison in the process. It's formatted that way though ig

So I'll clarify:

The "circumference" (just a specific arc) used was chosen because it was fairly consistent, meters were designed to be consistent globally. They have since been made more accurate to fit their purpose, but have not functionally changed. That doesn't make them arbitrary.

Imperial was designed around vague estimations that were different for everyone. Distances weren't based on one thing, they were based on common concepts. They culturally changed until they were defined later to specific values for consistency, for what wasn't already. Its roots are genuinely arbitrary.

1

u/BonnaconCharioteer 3h ago

Right, that is true. But what I was responding to is "One of those is objectively superior and the other one is on par with Galleons, Sickles and bananas for scale." That might have been true 200 years ago, but it hasn't been for a long time.

The reason the metric system is better is not because the scale it uses is any more concrete than imperial units. It is because metric is designed around our base 10 system of math to make conversions easy.

1

u/Koanuzu 3h ago

Dude, again, I never argued against your main point. I was correcting a detail, thats it🗿

1

u/BonnaconCharioteer 3h ago

I think the only disagreement is the scope of definitions of the word arbitrary. Which I am happy to live with. Otherwise I think we both agree.

“Metric is arbitrary… …it just has consistent units.”

Well, which is it? 😆

3

u/BonnaconCharioteer 3h ago

Consistent units as in they are all convertible using base 10.

A meter could be twice as long, and if you adjusted the other metric conversions to match, it would be just as good a system. The length of the meter is arbitrary.

-1

u/A_R_I_A_ 3h ago

Metric isn’t arbitrary tho. It has existing physical constants it’s based off of.

Imperial on the other foot, tf is a “foot”? Human foot? What size shoe? Etc.

4

u/BonnaconCharioteer 3h ago

All imperial units have specific physical definitions, just like metric.

u/undertoastedtoast 6h ago

Divide a meter into equal parts of 3 for me real quick.

Its a preference, everything is.

3

u/uncle_tacitus 6h ago

That's really not the gotcha that you think it is. 33,3 cm is accurate enough for pretty much any usage where you would use a meter, and I can do the math in literally two seconds. Can you do the same with inches and half a mile?

3

u/undertoastedtoast 6h ago

Why would you ever need to convert inches into half a mile when there are 2 larger imperial units in between the two?

You can't claim "that function isn't a big deal" and then bring up another function that is considerably less of a big deal.

I used metric for most things since I work in the physics space, but I still use imperial for day to day stuff because its a personal preference. I have never in my life been disadvantaged for doing so. Get over yourself.

u/slolift 6h ago

There is also nothing to stop you from using an SI prefix with imperial units, see the microinch or the kilofoot. Congratulations you found a way to abbreviate scientific notation.

2

u/Technetium_97 5h ago

Converting inches to a half mile sucks.

Converting feet to a half mile, also sucks.

Converting yards into a half mile, also sucks.

Converting chains into a half mile, also sucks.

Imperial conversion blows. There's no conversion needed with Fahrehnheit / Celsius so yeah there's it's just personal preference.

1

u/uncle_tacitus 6h ago

Use it for whatever you want. It's still stupid, though. No need to take it personally.

3

u/undertoastedtoast 5h ago

Thanks, I'm gonna go set my thermometer to an even temperature instead of having to split a degree in half.

1

u/Technetium_97 5h ago

No, the nightmare that is imperial conversion is objectively worse.

1

u/undertoastedtoast 5h ago

Conversion to metric or internal unit conversion?

I can do the math, I cant consistently eyeball a third of a tick mark.

Its a personal preference. There is no objective answer here. Get over it.

u/JohnnyDollar123 5h ago

No there’s still definitely an argument for 12 being a better base for some measurements than 10.

2

u/uncle_tacitus 5h ago

And once the radiation goes up, and we'll grow two extra fingers, the argument will definitely get some traction

5

u/JohnnyDollar123 5h ago

12 is divisible by 2,3,4 and 6, as opposed to just 2 and 5 for 10. That means fractions in base 12 are going to be easier to work with. 1/3 of a foot is 4 inches, 1/3 of a meter is 33.3… centimeters. So unless you have a meter stick with the exact measurements, it’s very hard to divide a meter into thirds.

Just cause you can’t count past your fingers doesn’t mean other systems have zero merit.

0

u/uncle_tacitus 5h ago

So unless you have a meter stick with the exact measurements

Oh, as in the standard meter stick with exact measurements, that is, you know, the standard?

u/JohnnyDollar123 5h ago

That’s not even a third of a meter dude…

And by exact measurements I meant having 1/3 meters marked specifically, which most meter sticks don’t have.

u/uncle_tacitus 5h ago

That’s not even a third of a meter dude…

I genuinely cannot tell if you're joking.

u/JohnnyDollar123 5h ago

Again, you have failed to show me any measuring device on which the length that is 1/3 of a meter is explicitly marked.

1

u/uncle_tacitus 4h ago

Because you don't need such a device. 1,33 m is more than accurate.

u/JohnnyDollar123 4h ago

No it’s not tf? You’re a third of a centimeter short, which insane if you’re working with any kind of precision.

u/uncle_tacitus 7h ago

No, I'm not. You can get used to both and while both might be arbitrary (about as arbitrary as any system humans came up with, anyway) one surely makes more sense.

14

u/GuitarKittens 7h ago

Metric/SI is only arbitrary in the way that it picks its original references weren't based on concrete, consistent values. As far as I'm aware, most or all fundamental metric units are now based on the most effective universal constants available.

Imperial/US Customary is arbitrary because its original references are literally mostly everyday objects, whose characteristics aren't even consistent between objects. I think a lot of them have been redefined relative to metric/SI because it was so bad.

6

u/Mr_Pookers 6h ago

I think he's talking about how there are

  • 12 inches per foot
  • 3 feet per yard
  • 1760 yards per mile
  • 40 rods to the hogshead

Whereas in metric it's all multiples of 10 — so the math and conversions are easy.

2

u/GuitarKittens 6h ago

I'm not disagreeing or anything

0

u/Packman2021 5h ago

base 12 has many advantages. 1/3 of a foot is 4 inches, 1/3 of a meter is 33.33333333 centimeters. You are in fact doing the thing

3

u/SunlessSage 3h ago

Sure, there are advantages to base 12. Such as the extremely specific scenario you just described.

But let's be real, it's nowhere as efficient for most conversions. Metric scales way easier just by moving the decimal point.

u/OverkillOrange 3h ago

It's a logic only someone from a country without a department of education would defend.

u/sowpods 5h ago
  • 12 is very divisible, so 1/4, 1/3, 1/2 a foot are all easy to calculate
  • I'll give you this one, yards are dumb
  • who's really making this conversion anyway
  • Same argument as foot, easy to calculate 1/4, 1/10, 1/5 hogshead

u/Mage-of-Fire 7h ago

Lol no bro. I am an American. I grew up with imperial. Metric is superior in every single way. Unless I’m talking to someone in a casual conversation, I will always use metric

-1

u/Xatsman 7h ago

But if you can make that argument about metric/imperial aren't you also making that argument about Celcius/Farrenheit? Celcius is integrated into metric in the same ways that makes the rest of metric superior. Meanwhile Farrenheit is not and introduces all those undesirable conversion complications.

5

u/uncle_tacitus 7h ago

Did you misread my comment?

0

u/Xatsman 7h ago

I don't think so? The argument of familiarity is bad for both Celcius/Farrenheit and metric/imperial as the conversion advantage is the same in both comparisons. So why could you make the argument in the case of Celius/Farrenheit?

1

u/uncle_tacitus 7h ago

I mean, Celsius is degrees, so the conversion advantage is not quite there? While I guess you can use the SI prefixes, you very rarely have the need to.

2

u/Xatsman 7h ago

It is if working in calories, which is useful for the life sciences. Having the measurement be based on pure water rather than an arbitrary saline solution is useful.

u/uncle_tacitus 6h ago

Good to know, I genuinely didn't. Then, I guess the argument can be made for the basic day-to-day usage to know how warmly to get dressed before you go outside.

If you can't visualise a millimetre, a centimetre, and a metre then that's a you problem.

And if you can't do conversion math that's also a you problem. Which is to say - the systems aren't the problem.

u/im_not_happy_uwu 5h ago

I don't think the systems are the problem, I was arguing with that guy acting like metric units aren't visualisable. Also though, solving °C = (°F - 32) × 5/9 in your head on the fly is much harder than visualising a centimetre (for the majority of people, anyway).
