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.
