40 below the lowest possible temperature? -313.15Β°C
Yeah -40 K overflows and becomes 18,446,744,073,709,551,535 K
-72 Rankine
One time my brother and i were testing eachother on our conversion (yes we are both very cool) and he gave me -40F just on a whim and i was trying to do it quick ad not accurate but it was just so plainly -40C that i couldnt believe it and we even looked up graphs and shit to see wtf. That was how i learned that one
It's pleasant here at the moment. 35/95 and 20% humidity. Small thunderstorm passing through.
30 degrees Fahrenheit? Hell yeah. It's practically tropical. If it's sunny as well, I'll be rolling my windows down.
(Not me in pic, but I've been him)
Right, it's barely freezing. And you work up a good sweat shoveling snow
Today is 42.2 C for me today. Then you factor humidity on top of that and it becomes like the gates of hell. Then I remember that I live in dallas and I basically already am in hell.
The European mind can not comprehend...
Friday looks pretty chill. Something to look forward to!
I lived in Dallas for 3 years. It is hell. I'll be praying for your escape.
We do now, where we live in France we just had 44Β°. So my condolences and please stay stay safe out there.
That sucks. Yeah - we have those temps in Texas for months at a time, but at least we have air conditioning most places.
It's also one of the reasons development is so hostile for pedestrians and cyclists here. We design everything around taking air conditioning with us wherever we go, which leads to car-first development.
Oh shit. Honestly I feel more for you guys than me. We have infrastructure built for it. Everything has AC. I even just put a window unit in my bedroom to take some load off the older main unit that has been struggling to keep up. But over there you were never built for that kind of heat. I wish you all the best with climate change.
I flew to San Antonio a few yewrs ago. I remember it being about 10 degrees cooler than Tulsa.
I didn't go outside in Dallas, though.
I was going to make snark remarks on the fact that a lot of people live in hostile environments and it's not super sustainable because we need climate control year round in every building and cars, but I live in Canada and it would be pretty hypocritical given the fact that I need climate control most of the year too. In fact, sometimes in winter when I watch the endless ballet of machinery burning oil to plow and move the snow, I wonder why we go through such trouble to live here.
I guess we get used to a lot of things. However 42C is too much for my taste. I go vacationing in the Caribbean where it's usually around 30C, and it's pretty much my limit.
What's funny is that I used to live in Phoenix for a year. I would happily take the higher dry heat over the almost as high wet heat. When I lived there it was like walking into an oven and you could feel your sweat pours opening. But the sweating evaporated quickly and provided cooling as long as you stayed hydrated. Shade works and you can see how the natives protected themselves from the sun and had passive cooling that worked. In the wet heat it is more like Satan is pissing on you and you have no hope. Your body is dumping sweat and it does nothing because the humidity is too high to evaporate. Shade? Worthless beyond the immediate sun protection. A few degrees at most. Without AC you will only cool with high winds or a fan.
Fun fact I never knew until living there: when it hits 112 (and it does) the airport has to partially shut down and divert all non-high-temp aircraft. The tarmac is so hot it will pop normal tires at a high rate. So unless you have the expensive higher temp rated tires for planes based out of high temp areas, then you can't land there when it is too hot.

Iβm slowly trying to convert myself to metric. Temperature is a hard one for me because itβs so ingrained in my psyche.
Length is easier. 440mm is much easier than 17 21/64 in. Plus all the CAD software I use is easy to switch to metric. Weight isnβt hard either since most of the maker things I use (filament/resin) are in metric. My doctorβs office even weighs me in kg thinking they can sneak it by me. I know what 92.4kg is you cheeky bastards.
Yeah, temperature is weird like that.
I'm an American, but one with an education and an appreciation for the one true system, SI, which is pretty close to metric.
Meters and kilograms make total sense to me, even if I'm conditioned to think in feet and pounds. But temperatures in Celsius just don't click. I have to consciously try to remember some equivalent Fahrenheit values to get a feel for it.
If you told me the barometric pressure in Pascals I'd literally understand that more quickly, since I deal with pressure measurements and settings at work.
I'm very similar. I have even lived in Europe a couple of times. But I don't even try to think in Celsius anymore, I just don't see a benefit and my brain rejects it. 90% of the time when I'm boiling water it's high up on a mountain and it boils below 100C in elevation. Also who cares if the water is 95C or 200F, it's not as hot as I'd like it to be.
I am the same way. For me I just memorized 2 C to F conversions and work it as a relativity from there. 22C is about 72F, the perfect inside temp to me. Then because I live in a hot place my other anchor is 40C being 104F. To me that is the threshold going from "fuck this is hot" to "shitty hot, avoid outside".
I would recommend just memorizing some key anchor points that are normal for your climate and learning from those.
Thatβs a very good idea. I may start doing that. I should convert my home thermostat but Iβm pretty sure my wife would balk at it being set to βso coldβ (23Β°C or so)
For april fools one year I released a drawing package in metric. Merriment was had.
Mostly by me.
Maybe this is from growing up in a place with seasons, but 30C to 30F is a comfortable temperature range and I would be quite pleased to live in a place where those are the extremes.
