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.

    I've used both customary and SI measures for daily living and the main difference is that the customary measures are mainly defined in an anthrocentric way. Your personal foot is unlikely to be a foot, but you'd learn the relationship between yoru foot and an actual foot and you can use them to estimate lengths. Same goes for most of the other lengths. Time is a mess in every system we've ever designed. Time measurement is literally the measure with the most room for improvement, but nobody has ever gone about fixing it. You can't do much about the length of a year, or the actual duration of a day, but there's no inherent reason why we couldn't redefine the hour to be 20 per day, a minute to be 100 per hour and the second to be 100 per minute. We could also make every month 30 days and add the remaining 5 days to the first 5 odd months and put leap year day as November 31st.

    It's never going to happen, you'd have to have the entire world changing all at once and then have to deal with the issue of dates and times from before that point not matching even remotely.

    One of the great things about the measuring system in America, is that while it's backed by SI measures, the increments are much easier for humans to use. Everywhere you go, you're carrying most of the things needed to estimate measures.

    Time and Math are fun...

    364.24.... days around the sun
    360 degress in a circle or face of a clock????

    360 is nice because divs by 12 nicely. So also divs by 24 and 60 nicely! And making gears to move them... again nice math.

    Did you know that Feburary was the LAST MONTH of year. Julain calendar. IT is why is shorter than others Orignal calendar was a 12 or 13 month calendars. Roman standardized it. 31,30,31,30,... days months The Julius (July) and Augustius (Aug) wanted their own months with same number of days. Remember Sept->7, Oct->8,Nov->9 and Dec->10.

    Dont even get into current different between Europe and US Calendars.... Europe Weekend is on right SAT, SUN. So SUN is day of rest (New Testament/christian based). US Weekends Sun left, SAT right. So SAT.... Sabith is the last day... day of res (Old Testament/Hebrew/Jews based)

    It its that US based match Genesis the best... Sun (heavens), Mon/moon (earth), then 4 norse gods Tue, Wed (Oden) Thu (Thor), Fri, the Sat (Sabeth/day of rest)

    They talking about virus are left encoded in our DNA. Now you can see human history encoded in Math, Time, Calendars
