I'll grant that farenheit has merit, but for me, the foot/inches distance works a bit better for casual measurements, and stuff that doesn't have to be very precise.
Beyond maybe someone's height, I'd rather work in metric. I'm also very much in favor of celsius and I still have trouble converting between the temperature scales. I grew up with temps in degrees C, and height and some sort distances in feet/inches. IDK, I'm weird.
The date thing drives me nuts though.
