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.

    > This is because it is a lot easier to relate to the difference between 5-ft 6-in and 6 feet than it is between 1.68 and 1.83 meters (or 1676 and 1829 cm),

    For you maybe, not for everyone!!
    This may be only true if you use imperial units, if not, it is exactly the opposite!

    For me, 1.68 and 1.83 are totally different and well understood difference ... 5ft 6in and 6 feet both looks to me like a small child (around maybe 7 years old)
    It just a matter of what you are used to. Every time some country change their coin (mostly same value range, like in Europe, for the euro, not the 10milions from zimbabwe [banknoteworld.com] to try to solve inflation... think on traveling to another country with a different coin, if your country never changed coin) , people feel hard to understand the new value, it feels uncomfortable... but with time and more unit use, you start to learn it and later found that the old unit is the one now that feels uncomfortable
