I'm not arguing on Fahrenheit's behalf or saying it IS more precise. I just said it "feels" more precise because you have finer increments in whole numbers. 70 degrees F is about 21 degrees C while 90 degrees F is about 32 degrees. 20 degrees of increment in F versus 12 in C which feels more precise. It's the same way metric length measurements feel more precise because there are whole number millimeters rather than fractional inches.
I have no strong opinion any one way, other than I feel like everyone should endeavor to be comfortable converting between various systems of measurement.
I think I came across as saying something different than I intended. I wasn't arguing that Fahrenheit IS more precise. I was saying it feels more precise.
If I'm measuring a length, then metric feels more precise. I can measure 1035mm in a nice, whole, number while 40.74803 inches is a length I can't measure well with a measuring tape and I'd probably end up calling it 40.75" which, even then, still isn't a whole number. I'm just talking about the perception, not the actual useful nature.
