[Gatac]

While I agree that there's countless vagaries in the Celsius scale (re: boiling point - what about the salt content of your water?), it is easier to reconstruct as it only requires a fairly common substance (water) going through two aggregate changes. If you want a scientifically solid scale, try Kelvin, which is fixed through absolute zero and the triple point of water.

To me, it's not a valid defense of Fahrenheit to say "Celsius is also whack!". Yes, it is, but Fahrenheit is the worse offender, and we should pick the lesser evil instead of wallowing in our temperature scale misery and sticking with what we have because it's all hopeless anyway, which is the vibe I'm getting here...
