  Fun fact, -40C and -40F are the same temperature.

  Then 575K and 575F are the same.

    Also -40C / -40F and 575K / 575F is the temperature of the center and edges of a hot pocket.

      I hate to be the good time ruiner, but unlike -40, it’s not on the nose.

      Still, really cool that it’s as close a conversion as it is.

  So you’re saying, that we should switch to specifying every temperature as a nice 69 and just switch out the unit?

  69C° is just sauna

  • Caitlyynn@lemmy.blahaj.zone ⁨2⁩ ⁨weeks⁩ ago

    A pretty cold one, too

    It’s not a real sauna if it’s less than 80 °C

    • jol@discuss.tchncs.de ⁨2⁩ ⁨weeks⁩ ago

      Depends if it’s a steam sauna.

    but 69 F is nice

  21F…someone grew up near the equator

    I mean it is literally below freezing so even if you’re the tough kid wearing shorts in the winter the above depiction is not inaccurate.

    • angstylittlecatboy@reddthat.com ⁨2⁩ ⁨weeks⁩ ago

      Yeah, but the other two cold ones are unsurvivable weather. 21F is very survivable.

      I didn’t see that SpongeBob ep but if it was the ocean it wouldn’t be frozen at 21 F

• someguy3@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

  21F is just jacket weather.

  • mipadaitu@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

    Only if it’s windy and cloudy. A calm sunny day at 21f is fine for walking around in shirtsleeves.

      Depends on how acclimated you are. Right now, for me, I’d be freezing, but if you caught me when I lived in North Dakota, sure.

    Basketball shorts and hoodie is appropriate no matter the season.

  21k and 69k are cold that time would dialate significantly at those temps

    This has me confused.

    Temperature can be used to refer to how fast the atoms are jiggling (kinetic or phonon temperature) or to how messy, disordered (opposite of ordered) a system is.

    Time dilation is a relativistic effect where time appears to go slower when you are looking at something that has a very high speed (near light speed) compared to you (relative velocity). Can also happen with mass because gravity is acceleration, thus related to velocity.

    If the atoms are jiggling slower, relative velocities only shrink, so you’d expect to see less relativistic effect. I am not aware of any relativistic effects due to thermal motion in normal conditions (room temp, atmospheric pressure), so I don’t know how they’d appear when relative velocities only decrease.

    I am really interested where you got this temperature - time dilation link from. Can’t seem to crack it.

      Yeah their comment doesn’t seem right to me. After a bit of googling I found this answer talking about heating things up to see relativistic effects, however because the velocities of the atoms in an object that has been heated up are random it’s most likely not possible to detect any relativistic effects. …stackexchange.com/…/is-there-a-relation-between-…

      I was taught that any energy exerts stress on space-time and because of that removing energy, lowering temperture, causes dialations.

    k is the thousands multiplier. Kelvins are symbolised as K

    So twenty thousand kelvins would be 20kK
