I did find one thing in her piece I agreed with:
Fahrenheit is superior to Celsius for describing weather temperatures among "regular people." Why? Perhaps it lacks logic, but in a very practical sense, 0 degrees is about as cold as it gets (and as cold as you want to be) in places where people usually live. Any below-zero temperatures emphasize just how cold it is. 100 degrees is similar: it's about as hot as it gets, and as hot as you want to be. Sure, Fahrenheit could be tweaked (e.g., to make 100 degrees the exact human core body temperature), but the current scale works well enough for casual use.
Kelvin makes sense for science, with 0 indicating absolute zero.
I actually don't think Celsius makes sense for much of anything. Maybe cooking?
Of all the metric units I agree that temperature is the most arbitrary. Like anything else, however, it only seems non-sensical to you because you're not used to it. I dove into it a couple of years ago in order to prep myself for extensive international travel and found that it works for the gradations of temperature we care about. <0 is "freezing", <10 is "cold", 15 is "cool", 20 is "pleasantly cool", 25 is "pleasantly warm", 30 is "warm", 35 is "hot", 40 is "really hot", and 45 is "unbearably hot" (think Phoenix).
However, no one will ever convince me that other metric units are un-American or communist or whatever. Imperial weights, lengths, volumes, etc. are just plain idiotic. Why should I have to remember the relationship between a fluid oz, a pint, and a gallon? Or how many yards in a mile? God help you if you need to convert acres to square miles (or cubic feet to gallons). The metric equivalents are self-descriptive (e.g. deciliter vs. centiliter vs. liter) and the relationships between different parameters are easy to remember (e.g. a cubic meter equals 1000 liters; one cubic centimeter equals a milliliter). Oh how I wish we were on the metric system.
EDIT: Also, only three countries in the entire world are not primarily on the metric system: Liberia, Myanmar (aka Burma), and the USA, although apparently Liberia and Myanmar are on the road to conversion. That's really some stellar company
