I've always thought Fahrenheit was the better measurement in regards to weather. 0 F is uncomfortably cold, 100 F is uncomfortably hot. It makes so much sense for the weather. 0 C is freezing, 100 C you are dead. Of course, for most things Celsius makes more sense, and even though I live in the US I don't even know how to measure computer temperatures in F, it just sounds crazy. When it comes to weather though? Fahrenheit is where it is, in my opinion.
Please guys, I know plenty of you will disagree with me, that's okay, this is just my opinion. Please don't get upset I know metric is generally better!
In fairness to Fahrenheit, you can round it to a whole number with a lesser difference in feel. That's more for feel though, for measurements of temp in cooking or chemistry, Celsius is useful due to boiling point.
