At face value, measuring the temperature using Celsius instead of Fahrenheit seems to make a lot of face sense. After all, the freezing point of water is a perfect 0 degrees Celsius — not the inexplicable 32 degrees in Fahrenheit. Also, the boiling point of water in Celsius is right at 100 degrees (Okay, 99.98, but what's a couple hundredths of a degree among friends?) — instead of the awkward 212 degrees Fahrenheit.

Celsius is also part of the much-praised metric system. It seems as though every developed country in the world has adopted the metric system except for the United States, which still clings to tge [sic] older, more traditional measurements. Finally, scientists prefer to use Celsius (when they're not using Kelvin, which is arguably the most awkward unit of measurement for temperature). If it's good enough for scientists, it should be good enough for everybody else, right?

Not necessarily. Fahrenheit may be the best way to measure temperature after all. Why? Because most of us only care about air temperature, not water temperature.

[...] Fahrenheit is also more precise. The ambient temperature on most of the inhabited world ranges from -20 degrees Fahrenheit to 110 degrees Fahrenheit — a 130-degree range. On the Celsius scale, that range is from -28.8 degrees to 43.3 degrees — a 72.1-degree range. This means that you can get a more exact measurement of the air temperature using Fahrenheit because it uses almost twice the scale.

    Not entirely. Yeah, conversions are a bitch, but a bookcase is really built sized with cubits and hand spans, which translate better into feet and inches. The body is the basic unit of measure, from which meaning of all the other measures are derived. Yes, it's highly individualized and variable, which is why standard measures are needed for communication. And avoiding conversions is what the metric system is about. Unfortunately it's basic units aren't convenient sizes for a lot of things. So a pound is a unit of force, where a kilogram is a unit of mass. They don't really convert easily, though sloppy conversions are often "good enough".
