Fahrenheit is the way to go.
Taking this opportunity to argue why Fahrenheit over Celsius makes way more sense. Fahrenheit is essentially based on a scale of 0 to 100, which is a scale we use for most things in life. Yes we can go below 0 or above 100, but it's such a perfect scale to understand exactly HOW hot or cold something is.
It's 70 degrees outside? Wow, we're at 70% heat. I bet that feels really nice and not too hot. Oh no it's 100 degrees so we're at 100% heat? Probably want to stay inside today. Water freezes once we get to 32%? Makes sense, that's pretty cold. I'll need to wear a winter coat. 0% outside? No way I want to go out in that.
In terms of understanding how how or cold it is outside, looking at the temperature as a number out of 100% is a perfect way of understanding that and having a frame of reference.
Celsius is so dumb. A 70 degree day in summer sounds great. 70% heat, not too hot, not too cold, just right. But convert that to Celsius? It's 21 degrees in the summer? What does that even mean? Stupid.
Also because of the way the math works, the scale for Celsius makes no sense. It's 0 degrees out in the U.S., that's -18 Celsius. But if it's 100 in the U.S., that's only 38 Celsius? What kind of stupid scale runs from -18 to 38? 0 to 100 is the way to go.
Imagine if test scores ran from -18 to 38. Would you support this nonsensical scale then?
To be clear, I'm on board with the metric system and I definitely don't think the U.S. does everything right. But Celsius is trash.
to a european like me 90 '%' or 20 '%' human comfort would be very confusing - you could probably guess that one is hot and the other's not but I'd have no point of reference until I convert it to Celcius. I think the numbers that someone grows up with will always make more sense no matter what
I mean we use scales from 0 to 100 in every field. -18 to 38 is a scale used absolutely nowhere.
But I agree Humans can get used to pretty much anything, and once they do - it's all they will prefer over the unknown.
So 0°F was defined as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (why in the world?). Originally, 90°F was set as human body temperature, which was later changed first to 96°F, and now it's about 98.6°F.
Celsius is just: 0°C is the freezing temperature of water 100°C is the boiling temperature of water
Nobody uses a scale between -18 and 38. People in countries using Celsius just learned as a child that body temperature is 38°C, that's all. -18°C has no special meaning to us.
At 0°C outside it's freezing (32°F). 10°C is quite cool (50°F), you'll need a jacket. 20°C is a comfortable temperature for me, if it's sunny (68°F). 30°C is getting rather warm (86°F). 40°C is hell outside, or a bad fever (104°F). To boil water, heat it to 100°C (212°F).
I get that this seems confusing at first when you're used to completely different orientation points, but for people who are used to C, it's very intuitive.
