[color=#000000ost_uid0][quoteost_uid0]There's a one-to-one function that accurately relates temperature in F to temperature in C, so one temperature scale is just as stable (or unstable) as the other.[/quoteost_uid0]

But those Foreignheat values can't be independently verified. Celcius can. You can take a pan of distilled water down to sea level, boil and freeze it (possibly in the reverse order) and calibrate a thermometer. You can't do that in F (the jokes wears thin after a while, and it's too long to type the proper way) because Dr F's body temperature is currently the same temperature as his coffin, and an average winter's day in Vienna is not the same now as it was in 18-whatever.[/colorost_uid0]
