I'm originally from the US. Since living in Europe, I can't believe how much easier the metric system is. I can not convert between the two so I dropped imperial. The only time I deal with it is when I call family in the states.
I do recall, when I was a kid, they tried to convert the US to metric, but it failed miserably.
Fahrenheit is better for weather, and I'll fight anyone about it.
We use Celsius in the lab because it makes math easier, it's great.
But Fahrenheit is basically a 0-100 scale of how hot it is outside and that makes perfect sense for describing outside conditions relative to human sensory perception.
