0 Kelvin = 0 Rankine
Also, both °R and °Ra are Rankine. So 3 of the 5 people in the bottom picture also agree.
And the other two can shake at -40
I think none of K, R, and Ra may be pointing at each other.
Hmm. To my eye, K is obviously pointing at either R or Ra (and F), R has to be pointing at Ra (and K or F), and Ra is pointing at R or K (and C).
K is obviously pointing at R because Rankine is an abomination in the same vein as pound-mole and thousands of an inch.
Motherfuckers, metric is right there, get your disgusting units out of here.
Anyone who uses either of these units in the last 40 or 50 years, I would like to physically fight with you. I have never thrown hands.
°RA sound like the sun’s temperature
1°RA = 5500°C / joking
As far as equations go, “one degree RA equals 5500 degree Celsius divided by joking” is unusually abstract 🤔
-40C = -40F
Also 0lbs does not equal 0kg when there’s no gravity.
huh?
Mass doesnt change with gravity
Typically, lbs is not mass, it’s weight/force.
isn’t that lbf?
The pund itself is defined as 0.45359237 Kg
Lbs can be lbf or lbm, but usually is referring to lbf, which is 0.4536 kg at 1g.
when comparing to kg I will assume the mass unit, since comparing a mass value to a force has no meaning.
no mass multiplied with gravity still results in no force, 0 Lb = 0 Kg; 0 Lbf = 0 N
Yes, but 1kg also results in no force, so it’s a trivial statement.
Gravity? What does that have to do with mass
Nothing in this context, but it can have a lot to do with force, for which pounds is the US customary unit.
when compared to a value in Kg, the only logical interpretation is the mass pound. If it were lbf, the si unit conversion would be Newtons.
Having the same name for two different, but easily mixed up units is really annoying haha
It’s clear from context clues that they don’t mean Force. As kilograms are an indicator of mass, not force. It’s not our fault that US’ imperial system is silly.
Imperial is a British thing, and the quantities differ significantly from US customary.
perhaps, but the US uses it.
Nope. As I said, the US customarily uses US customary units. They ARE NOT identical to “Imperial” units, despite the coincidental naming.

Kelvin is objectively the most accurate. Celsius fans cope.
Er… every system of measurement is accurate, tautologically.
0°F = 0°F because 0°F = 0°F, by definition.
I dunno. I wouldn’t be surprised if somebody took the time to invent fuzzy measurement unities.
I wouldnt call farenheit accurate, but these days it is because its a static number in celcius, which is also an accurate and static measurement that can be repeated billions of times.
Not because 0 is 0 :p
In the original farenheit definition my 0 farenheit was not your 0 farenheit heheTouché but you know what I mean. It’s the most logical to have absolute zero be zero.
But there are multiple that have absolute zero at zero
0°R=0KMaybe in some scientific settings, but nowhere else. Why would it be logical to use a temperature system in every-day life who’s base is set to a temperature that doesn’t exist on Earth? Celsius and Fahrenheit are human-scale measurements, useful in daily applications. Celsius is a bit more logic-y, and Fahrenheit is intuitive.
Only Kelvin is valid thermodynamically because thermodynamics often needs absolute temperature for the math to work out right. Rankine is only for masochistic idiots who like fucking up their math and having extra stupid constants all over the place to compensate for their shitty unit system.
Perhaps, but that was not the statement. The statement was:
Kelvin is objectively the most accurate.
Functionally, a measurement system cannot be inaccurate. You might define a new temperature measurement in blargs, and define that the room you’re in right now is 1 blarg. It is now an accurate statement to say that the room is 1 blarg. At the time of measurement, it is not possible for that statement to be inaccurate.
For some reason my brain dropped the ‘L’.
Sitting here wondering how Kevin does it…
They’re both calibrated against a stupid wet molecule that carbon based life on this planet is addicted to.
Introducing: the Nihon. 0Nh is the freezing point of Nihonium at 1 bar pressure, and 100Nh is the boiling point. Well, theoretical freezing and boiling points. Nihonium is one of those elements that doesn’t stick around long enough to be studied. But we thought really hard about it, did some shit with particle accelerators, and we’re pretty sure these numbers are good.
The bar is defined to be close to the atmospheric pressure of one random planet called earth, why choose that as your pressure unit?
It’s a nice day today. Can’t be more than 300 degrees
I’m not so sure
I’m coping, Celsius is just as accurate as Kelvin, because it based on it.
Kelvin - 273.15 = Celsius
Depends on your measuring tool. A thermometer that measures in K but has an error margin of +2 to -2 K is less accurate than a thermometer that measures in F and has an error margin van -0.1 and +0.1 F
Would be better ordered like F° C° K° R°
You mean K° F° C° R°epeat
Found the Americans.
I kid, but it’s °C, not C°
And K had no degrees at all.
The other two units are not mentioned in this household.
Fahrenheit is vibe temperature. It just feels good use bigger numbers to describe being very hot. “It’s 30 degrees outside” sounds hot but “it’s 100 degrees outside” is more expressive, like built in exaggeration. That could be why it is preferred by Americans.
No, it’s just because the US never really converted to the metric system. Degrees Fahrenheit are zeroed at the freezing temperature of brine, and there are exactly 180 degrees from freezing to boiling water because that was an easy number to divide (like the 360 degrees in a circle).
But really it’s because when you’re used to big numbers all your life, why would you limit yourself to puny smaller numbers
Seems like Americans also choose cars by this principle
Hello decimals.
Americans fear them.
To be fair, fractions are inherently superior
Decimals are just fractions for ppl who can only handle dividing by powers of 10
Farenheit isnt a vibe temperature, its just a bullshit unit of measurment that stuck around in the US.
If you wanted a vibe temperature, why not have 0 be comfortable room temperature and then negatives be colder and positives be warmer?
Or just use Celsius like the rest of the world.
They are called Canadians. The scale works like that for them.
30 degrees outside feels very acute.
This is an argument that gets rolled out a lot but the argument is also based on vibes.
Celcius having zero at freeing is actually useful with weather.
100 being boiling, is also nice for cooking.
The rest is arbitrary, and cope from US customary users who can’t accept that metric is the same or better in every single way.
there’s a whole host of temperature scales, some of which look similar, some look different, some scale the same at the same temperature difference but have different zeroes, and at least one works backwards. Thank goodness there’s only three you’re likely to see in the wild these days, I’d hate to have to keep in mind whether or not those degrees are not Celsius or Fahreheit, but… idk, Newton? Réamur? Rømer? Delisle?
More like only 4 than 3, at least in the us, I unfortunately run into Rankine at my job on occasion.
Welp, it is like Kelvin, just with Fahrenheit step.
Use molecular wiggles mw
I know the F C and K, but what are the others?
R is to F what K is to C. Ra is used sometimes because there are other R meanings.
Interval vs. Ratio
