As Italy swelters under dangerous heat, McDonald’s workers called a strike after their air conditioning broke in oppressively hot kitchens.

That’s 40c in normal units :)
Thanks. Whenever I see Fahrenheit units I have no fucking idea of what the actual temperature is meant to be
Yeah i know what u mean, and since the article is about italie which uses celcius its even weirder :)
I browse shit on Amazon Japan, and the sizes are in inches, eagle heads and football fields. We use the metric system here, Amazon!
Doesnt japan also drive on de left side of the road? Because ive noticed that countries that drive left tend to use mixed, like the uk uses cm and inch (also stone which i really dont understand). But thats just my brainfart
Should be just one. Banana for scale. ALL scale(s)
Yup, we drive on the left side ;)
Japan drives on the right. I think you are thinking of Korea. (They drive on the left)
Japan drives on the left side of the road. Korea on the right. Japan has right hand drive, i.e. the steering wheel is on the right
We drive on the left. Source: my driver’s license :)
I got this from https://en.m.wikipedia.org/wiki/Left-_and_right-hand_traffic#:~:text=LHT was used under Japanese,liberation from Japanese colonial power.&text=Japan was never part of,also drives on the left.

So the proper conversion from Celsius to Fahrenheit is F = 9/5C + 32
But an easy way to do it (roughly) from Celsius to Fahrenheit is double it and add 30.
To convert from Fahrenheit to Celsius is subtract 30 then halve it.
That’s a real lifehack!
One helpful tip I’ve figured out. 100 foreignheight is body temperature. So if it’s around 100°F it’s around 38°C.
A little helper to get a feel for it: 20°C is 68°F, 25°C is 77°F, 30°C is 86°F etc. Meaning, you just remember one or two combinations and then for every 5°C change it’s 9°F up or down
Or America could stop pretending to be special and just use the metric system.
Right? You’d swear they invented the imperial system the way they latch on to it. Fucking ridiculous.
I feel bad for american youth struggling in math and sciences. The imperial system has so much less connectivity between their units that the only way is to memorize all sorts of arbitrary numbers.
Apparently we yearn for our imperial chains
Yeah this really not helping, me at least :)
Nah. That math is so silly ill just ignore everything f
This has been the most singularly useful tip in trying to equate F to C. Thanks!
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 ] + 32Or 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 * CC = (5/9) * F ~= 0.6 * FI 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 ] + 32F2 = [ (9/5) * C2 ] + 32F2 - 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) ∆CSo, 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
Thanks, real geniuses to not mention the unit when using Fahrenheits and talking about Italy…
Isn’t it nice the US and Liberia are imperial bros?
Probably feels like 50 plus as they are moving around a lot.
