When I found out about this after Climate Town's video on the subject, I was so furious!!!!

Few things to point out:
Go vegan!!! Yes!!!
Lot more My Little Pony than I was expecting...
Destiny community's in there
Love seeing all the Pokémon :)
It's so backwards. Making this stretch of coastline walkable means more people show up, and if businesses realize this potential then they can capitalize. Makes sooo much sense
Hope Alexandria in Egypt can come to this realization some day
I think about the difference between the two using differences instead of absolutes. That looks like this:
It's kind of hard to do this calc:
F = [ (9/5) * C ] + 32
Or this one:
C = (5/9) * (F - 32)
I refer to those as absolute equations. You have to take into account the pesky offset everytime you want to convert. What if we drop it? This makes:
F = (9/5) * C = 1.8 * C
C = (5/9) * F ~= 0.6 * F
I refer to those as relative or difference equations because if you subtract a temperature from the other, you get the same thing:
F1 = [ (9/5) * C1 ] + 32
F2 = [ (9/5) * C2 ] + 32
F2 - F1 = [ (9/5) * C2 ] + 32 - { [ (9/5) * C1 ] + 32 }
= [ (9/5) * C2 ] - [ (9/5) * C1 ] + 32 - 32
= [ (9/5) * C2 ] - [ (9/5) * C1 ]
= (9/5) [ C2 - C1 ]
F2 - F1 = (9/5) (C2 - C1)
∆F = (9/5) ∆C
So, why is this useful?
Say you have a temperature in Celsius and want to go to Fahrenheit. Simply multiply that number in your head by 1.8 (or think of this as multiplying by 180° as in trig) and finally add to 32. So, 1 °C is (1 * 1.8) + 32 °F or about 34 °F.
Going the other way is a little bit weirder. I make approximations when going the other way by thinking of 180° and how that can be divided. So, 180°, 90°, 45°, etc. corresponds to 1.8 °F (1 °C), 0.9 (0.5 °C), 0.45 °F (0.25 °C), etc. I also approximate by choosing the nearest multiple of 5 or 10 °C (9 or 18 °F). So, 44 °F is between 41 °F (5 °C) and 50 °F (10 °C), closer to 41. It's off by 3, which is about 3.6, which is 2 in Celsius world. This means 44 °F is about 7 °C.
Hope you get the gist! Celsius really is better. I remember this in a pinch:
10 °C = 50 °F
20 °C = 68 °F
30 °C = 86 °F
40 °C = 104 °F
50 °C = 122 °F
Etc.
The freezing temps are a little hard since you cross zero into negatives, but the extrapolation can help
I was just responding to the first point made by OP. Didn't intend on commenting on the other stuff because either I agree or don't know enough to contribute!
There's a phone company out of Europe, Fairphone, that's striving to fix these problems. I can't really say if their specs are up to par or not (fwiw their newest phone can do 5G), but you can repair you phone with their Spare Parts offerings, like the selfie camera, earpiece, rear cameras, speaker, USB-C port, display, back cover, battery, etc.
Issue is that you can't buy it in the US or elsewhere, but there are some tricks where you can get it into the US/CA by going with Clove or Reship.
Phone looks to work best on T-Mobile networks, so AT&T or Verizon users might see terrible performance.
So, not panacea, but a decent solution for those willing to go down that path.
It's been great seeing the community grow. Hope this keeps up at a sustainable rate until Lemmy/Mastodon/Pixelfed/etc. become mainstays.
