Re: negative 450 degrees Fahrenheit
"Kelvin is never referred to nor written as a degree" is false. It never /ought/ to be if you are using it as an SI unit, but everybody does because:
a) it was what we were all supposed to say until 1967 anyway, (see for example http://astro.vaporia.com/start/kelvin.html ) and I was set in my ways by then, and
b) It makes more sense that blotting up some dubious pedantic brainfart just because a bureaucrat put it on a piece of paper.
