Comment on 98 degrees upstairs, ac stopped working at 8am.

  No one calls out decimals in Celsius. Unless you are measuring your kids fever. 38.1 vs 38.5 vs 38.9 you know that it’s time to ready the metamizole if it keeps creeping up like that

  0°C is the frost point of water. If you know it will dip below that during the night, you can prepare your plants, driveway, kids (I’m sorry my love summer is over), pets, clothes, etc the day prior.

  -40° is -40° though, doesn’t matter if it’s F or C. The best part of both scales.

  Copying this post I made elsewhere recently:

  I used to say this. But being a curious person, and one willing to test my own hypothesis, I decided to learn Celsius. Like, spend enough time with it to intuitively understand it, so that I could compare the two.

  Almost six years later, I haven’t switched back. I much prefer Celsius for weather. Having 0° at freezing is far more useful than I suspected it would be, and having less granular degrees gives them more meaning, which makes understanding them easier.

  Seriously, I struggle to express just how useful below-freezing temperatures being negative is. -5°C means so much more to me than 23°F, and that’s after thirty years of using Fahrenheit and only six of using Celsius.

  I often hear americans (even scientists) say that they prefer the Fahrenheit scale for weather forecasts, but I believe the perceived higher accuracy is an illusion. Forecasts aren’t that accurate for any given micro climate.

  For example, I don’t care if my weather forecast says 26°C or 28°C, I know it’s “short sleeves” weather and when I look at a few graphs at the end of the day, it’s been 25.6°C two meters above ground 100 meters south of me and 27.3°C in the garden, but only for 5 minutes etc.

    I often hear americans (even scientists) say that they prefer the Fahrenheit scale for weather forecasts, but I believe the perceived higher accuracy is an illusion. Forecasts aren’t that accurate for any given micro climate.

    When I switched from Fahrenheit to Celsius I used a rough heuristic to get the Fahrenheit value from Celsius. What I discovered was that my heuristic, which was rounded and would skip entire degrees Fahrenheit, matched most weather app’s Fahrenheit value.

    For example, if my app said 20°C, the other person’s said 68°F. If mine said 21°C, theirs said 70°F. If mine said 22°C, theirs said 72°F. If mine said 23°C, theirs said 73°F. It is very rare that mine has said, say, 21°C and theirs has said 69°F (or any temperature where the value was converted with decimals and then rounded).

    That is to say, my experience certainly seems to indicate that for people using the same weather sources but in Fahrenheit, the value was still rounded to the nearest degree Celsius, then converted to Fahrenheit and rounded again.

    That’s not to say you’ll never see 71°F or 69°F or other values that aren’t converted from an already rounded Celsius value, it all depends on what your data source is providing you. But nearly always, my rounded conversion from a rounded Celsius value matches what other people see in Fahrenheit.

    This makes complete sense, because most people cannot tell the difference between 70°F and 71°F. And it’s difficult to predict regardless.

  Nah, I agree 100%. Celsius is wonderful for computers and science, but the human-tolerable range is far too small. Fahrenheit is a human-based scale, with 0-100 basically corresponding to a percentage of how much heat a person is able to/forced to hold onto. At 0, you’re not really able to hold onto any heat; you quickly reach hypothermia. At 100, you’re forced to keep nearly all of your heat, and are only able to vent trace amounts; you quickly reach hyperthermia.

  It turns out, people function best when they’re keeping 40-70% of their heat (depending on how they’re acclimatized, which is determined by how much brown fat they have), so those are the temperatures that are most comfortable for us.

    I agree with the sentiment but -40F to 120F would do the job better
