Back when I took trigonometry, they taught me positive was counterclockwise.

I will blame trigonometry, because orienteering says it’s the other way around.

Another American thing maybe? Always been clockwise for me

Edit: ah duck me, trig goes the other way round, forgot, everything else is clockwise tho

Yeah, if positive was clockwise in trig, y = sin x would have a negative slope at x = 0, which I guess Albert Sine found distasteful.

(I made up Albert Sine. I don't know that there's anyone specific we can attribute the invention of trigonometric functions to. But I like to imagine him sitting at a desk scribbling right triangles by candle light and scratching his head as to how he'd go about actually calculating the sine, cosine, tangent, arcsine, arccosine, etc of various arbitrary values within his lifetime.)

100° = really fuckin' hot
0° = really fuckin' cold

0°C - pretty cold

100°C - pretty hot, grab a beer with you and remember towel under your ass

What's the beer for? To be paired with the human ham I'll turn into if I am exposed to 100 °C for too long?

Saunakalja (sauna beer) is a crucial component of Finnish cleansing ritual

100 is too much. The sweet spot is somewhere around 80.

I found 118 last month for the first time. It was extremely warm

It's the one part of Murica measurements that makes decent sense. Science aside I just want to know what to wear that day in a human scale.

Yeah, celsius users will be like "I can't understand this scientific celsius scale, how can I possible know whether it is saying I should wear shorts or a big fur coat. I wish I had a human scale".

For everyone from the real world, not fluent in retard units.

12 inches = 1 foot

3 feet = 1 yard

22 yards = 1 chain

10 chains = 1 furlong

8 furlongs = 1 mile

3 miles = 1 league

And here is my favourite 2 dimensional unit:

1 furlong x 1 chain = 1 acre

Edit: bruh.

What even is zero Fahrenheit? Isn’t it some random point above freezing that is cold but not that cold?

Yeah, 0F° is close to leave-a-faucet-dripping-lest-your-pipes-freeze weather. Quite a ways below the freezing temperature of water at standard atmospheric pressure.

it's a pretty interesting science experiment. it was the temperature of a mix of water, ice and ammonium chloride, which forms a eutectic mixture that stabilises itself at the temperature that fahrenheit chose as zero.

...he didn't write down the amounts he used though.

0f, you just walked outside of a station in Antarctica

100f, you walked outside in a city built in the middle of a desert during the daytime

-40, the temperatures the same in f or c, but you're not gonna like it regardless

I had to use Google Translate creatively to get this joke, but I'm delighted none the less.
