Obviously I was thinking of manufacturing new ones that don't exist in nature. I should have made that clear. Sorry. I misspoke. My bad.

No, I can't. So what? How does that affect its usefulness? It doesn't.

Did you know without looking it up that the original definition of the meter was 1/10,000,000th of the distance from the north pole to the equator through Paris or some city? Maybe. Maybe not. Is the meter any less useful if you don't know? No, it isn't!!! OK, if you need a quick estimate of the circumference or diameter of the earth, then it would be of some help. But for everything else it doesn't matter. And do you know the current definitions of all the SI units? I bet you don't without look them up.

Not as easy as you might think. The melting and boiling points of water vary with pressure. So you have to add what your standard pressure is. And then you have to produce that pressure. Easy? Not as easy as you thought. Ever hear of cooking times varying with altitude due to changes in atmospheric pressure? I have.

Later, to be more precise and more easily reproducible, it was later defined that 0.01 deg. C would be the triple point of water. And you'd have to add some stuff about kelvins in there to get what 0 and 100 deg. are. Not something you're going to do at home, but it doesn't depend on pressure. There is only one triple point. And did you know all that without looking it up? And do you know what the triple point of water even is without looking it up? And do you know the new standard without looking it up (newer than the triple point)? It doesn't really matter for normal everyday use, does it now? And simple? I think not!

Just like disk shadowing or mirroring. Not as easy as it first appears!!!

And again, please don't bring up the science lab bit. In science lab you use C or kelvins. In physics courses you typically use just kelvins.

I think it was the range of temperatures that were deemed useful in everyday life. Doesn't matter. It doesn't affect the usefulness of F.

Again you are missing the point. The vast majority of the time, no one needs to know any of this when using F. When you set the thermostat to 72 deg. F, do you really need to know any of this stuff? When you pre-heat your oven to 350 deg. F, do you need to know any of this stuff? You only need to know 32 and 212 and even then only some of the time. In places where the temperature reaches freezing, yes, 32 is a good number to know. But laypeople can handle it.

So I'm guessing you don't know the current definition of Celsius. But I know the current definition of Fahrenheit! 

F = 9/5 C + 32

And I didn't have to look that up. And if I don't have to do conversions, I don't need to know it anyway.

Also, I'm talking about using these temperature scales in ordinary everyday living. Not in the science lab. Not in the physics textbook. I'm talking laypeople.
