In that case, you should change the scale to match how hot/cold it actually gets outside. In many parts of the world, and even in North America, it regularly goes below 0F or above 100F.

"How hot it feels" is highly subjective. I would absolutely melt at 100F but feel fine at 0F, and nothing feels colder than those rainy windy days when it's 5C outside.

I use a binary thermometer. 1 is hot, 0 is cold.

The only temperature system that isn't arbitrary would tell you how spreadable butter is. Zero degrees butter is utterly not spreadable while 100 degrees butter is the maximum spreadability it could achieve before melting.

The stupidest thing about this that I always go on about is that they're saying the better scale is the one that goes from 0 to 100. i.e. metric. So why not use that for other measurements?

And if you only ever used it for describing weather, that would be an argument to make. But you use it everywhere, I mean just search for the term "cooking temperature" on Google images and you'll see a bunch of nonsense.

But even using it just for weather, this is still not a good argument, as the perspective of hot and cold is very very subjective, and changes constantly. To me, an outside temperature if 10C feels freezing cold in September, but it's reasonably warm in January. Or an inside temperature of 24C will feel amazingly cold on a 42C July day, but super warm on a -10C December night.

This scale presumes the non-existence of the state of "supa hot".

B... B.... BAKA!
