I think you're saying that where you live, the weather is usually between 0 and 100°F. Aside from the fact that outdoor temperatures aren't in this range everywhere, we don't only use temperature for weather. 100°F is warm to the touch, not smoking hot. 100°C is boiling hot. You sip tea at 60°C, and brew it at 80° to 100°C depending on the type. You cook chicken to an internal 74°C. A hair dryer blows air around 50°C. All of these are outside of 0-100°F. > I generally just prefer the Imperial system because of its practicality in everyday life Funny, most of us much prefer metric mainly for its practicality in everyday life. Edit: I'll add that aesthetically, 0°C is a really nice zero point for weather. Above 0° is the temperature that the snow starts melting, below is when the streets and ground starts freezing. Which side of 0°C you're on is the biggest pivot point for what it's like outside of any temperature.

> I think you're saying that where you live, the weather is usually between 0 and 100°F. Well let me clarify, what I was saying is that where everybody lives the temperatures tend to be within that range, which is why I think it's a superior measurement for temperature related to the weather - again just additional clarification which was missing maybe from earlier comments. Once you arrive at the point where you're measuring various things, I'm not sure it matters what scale you use so long as the values align as you expect. In other words, I don't really care whether I'm using 212 for the temperature at which water boils or 100 - it's just an association of values to action. You can swap between grams, ounces, pounds, milligrams, or kilos with your scale and it's not that important for day-to-day life. In terms of measuring temperature of things, like, say when chicken is cooked, I'm not really sure F or C is more practical. It's just different numbers.

  I live in one of the most populated cities in North America. The temperature on Saturday is forecasted to go down to -18°F (feels like -29°F with wind chill). It's not at all unusual for temperatures to be below 0°F in winter in much of the world. > Once you arrive at the point where you're measuring various things, I'm not sure it matters what scale you use so long as the values align as you expect. You can't have it both ways. The entire advantage you proposed for Fahrenheit is that the outside temperature is often between 0 and 100. It's a tiny aesthetic advantage that doesn't even work very well because 0°F isn't actually the coldest temperature we get and 100°F isn't the warmest. You're right it doesn't matter that much if water boils at 100° or 212°. It's just different numbers. But by the same token, it doesn't matter if the warmest weather is about 100°F or 40°C. It's just a different number. At least 0°C and 100°C are actual points that mean something and are relevant to everyday life, while 0°F isn't really anything. As I said before, the weather outside changes more at 0°C than at any other temperature.

    The steelman argument for Farenheit as it is, not necessarily the motivations behind it, has been fleshed out here: http://lethalletham.com/posts/fahrenheit.html http://lethalletham.com/posts/fahrenheit.html TL;DR: "The remarkable result here is that 0℉ is nearly exactly the 1st percentile of daily lows, and 100℉ is nearly exactly the 99th percentile of daily highs." NB: The context is the continental US.

      It's a pretty neat analysis, but it looks like the "nearly exactly" part must be a coincidence for the particular methodology and data they used (most significantly that it's based on 2018 weather). Fahrenheit was created in northern Europe, using the temperature of a salt water and ice mixture as the zero calibration point. It was later adjusted to define the difference between water's freezing and boiling points to be exactly 180°, since 180 is a highly composite number with many divisors. So off the bat, it's a bit odd that 0°F and 100°F would match the 1st and 99th percentiles of population-adjusted daily highs and lows in the US with that much precision. It's a coincidence already in the sense that the creator was not aiming for this. But it's also a coincidence because they used 2018 data, which was a particular warm year on average. (2012 was warmer, but I don't see any warmer years before 2012 in the National Weather Service's table which goes all the way back to 1875.) Average temperature across the US can vary by 3° or 4°F year to year. The population adjusted temperature should vary even more because it depends on lot on which weather systems hit the major population centers that year. I'm not sure how much the 1st and 99th percentile would change if they redid the analysis for a different year, but it would probably vary by several degrees. It's also kind of interesting that you would never have gotten this result before around 2012 or so, due to global warming.

        It doesn't matter if it's a coincidence or not. The fact that it works out that way still plays to its convenience and "good feel" in the US. Arguing that it's a coincidence isn't really relevant. I agree with the poster further up: I'm more or less good with all metric units expect temperature. While I still "feel" all the US customary units better than metric, I can intuitively "see" meters, liters, and kilograms. But Celsius continues to elude me, even after dating and being married to someone for 8+ years who grew up in a metric country.
