Title: Subaru prepares you for driving in temperature extremes...
Post by: K Frame on September 29, 2020, 11:38:47 AM
I just found this in my owner's manual...

"This displays the outside temperature between −408F (−408C) and 1228F (508C)"

So, I guess I'm ready for driving either on Mars or the dark side of the moon...


Edit in: Just noticed that that's a typo... -408 F is actually -222 and change C...



But, judging by the other sections in the manual talking about temperature, it looks as if they missed some periods... I think it should actually be -40.8 and 122.8...

Makes sense about the missing decimal place.  -40F would convert to -40C.

Just made me chuckle.

As I told my friend, who is also a Subaru guy, at least I'll know what temperature caused my Forester to melt and catch on fire.

Will the AC work on Venus?

Wouldn't see why not... at least until the concentrated sulfuric acid in the atmosphere dissolves, well, everything.

I think it is a coding error.  -40 [degree symbol] F to 122 [degree symbol] F.

I thought among the "woke" types things like periods (which look like decimal points) are now considered to be micro aggressions?

Good thing it only goes down to -40 F. If it went to -40 C, there would be trouble.*








* - a little intentional low temp humor there - I'm sure APS members will catch it.   ;)

Maybe Musk should have sent a Subaru to Mars instead of a Tesla.

Whoops. Said Mars, but meant Mercury, where it's just a tad warm most of the time.

Glad you caught that.  calibration below absolute zero is difficult.

Gets hard to to pump,that liquid O2 into the lungs.

"8" not "."

"8" be "°"

ETA I didn't notice that Fly320s had pointed this out previously. Thanks, Fly320s.

Rather than cramming unicodes into posts, e-mails, etc, I put a bunch of these symbols into a text file so I could just paste and copy.  I have a desktop shortcut to this file. Here's a sample:

SPECIAL OFT-USED SYMBOLS

degree   °
micro µ
obelus ÷
slashed zero  Ã˜
umlauts Ü, or ü
Ö, or ö,
pilcrow ( ¶ )
section sign ( § )

Simple, easy, works the proverbial "99%" of the time.

It was a revelation to me to discover that -40°C = -40°F back in high school and that for higher temperatures pretty much 9 ÷ 5 was equal to 1-1/2 and 5 ÷ 9 was equal to 1/2  for a rough conversion back and forth between the two scales.  While 5000°F is not really 2500°C it gives you a picture of where you are between the scales with what, an 11% error?

Meh, what's an 11% error between friends?  And at those temperatures, 32 degrees plus or minus is trivial.

Oh, and I got called out once for using "degrees Kelvin" ("°K") for the absolute scale of temperature.  Oopsie !

Nap time.

2500* C  x 2 = 5000.  5000 - 10%(5000) = 4500.  4500 + 32 = 4532.

Google says the same thing.  https://www.google.com/search?q=2500+degrees+celsius&rlz=1C1CHZL_enUS746US747&oq=2500+degr&aqs=chrome.0.0l4j69i57j0l3.6868j0j7&sourceid=chrome&ie=UTF-8

With the right resistors you can make your temp read anything you want it to.

Well, the idea was to get a general mental relationship between the two scales (at high values), not for obtaining publication quality values.  Sort of like a yard equals a meter and a quart equals a liter.

All "sorta."

What "kinda" gets to me is in this passion to convert all measurements to physical-constant related units is that sometimes it yeields unwieldy units.
 
Hey, I'm all for that, "in theory" but my favorite example of unwieldyness is Pascals for pressure.

Me, I kind of like "atmospheres" for pressure units (bar) because I can imagine 5 handsful of air compressed into one handful of air as "five atmospheres" (5 bar) of pressure rather than  5 X (1.01325 x 105) Pascals.

Note: :rofl:

Sure, I'm used to using pico, nano, and microfarads, and even "inches of mercury," but somehow that Pascal unit always amuses me.
