haha yeah I like that joke, and have used it before in good fun. The public in the US will never change. Hell, look at the UK. They officially went metric 50 years ago, but the public still clings to Imperial for a great many things: stone for weight, feet and inches for height, pints for liquid, etc. The only way to force that change is to... well, force it. Forbid the old system—make people use the new one. And the US gov isn't going to do that. But I agree with you, changing would make things easier. Celsius is ok. Easy enough to get used to. Doesn't make a lick of sense, tho. We are humans, not water. Not to mention limiting us to (basically) 0-30 feels less informative than having 32-100 to work with. Fahrenheit is by far the better system for humans.
