    Also let me point out one nice feature here - the freezing point is 0. Bellow it you can expect snow instead of rain, ice on the road, sidewalk, plants are in danger, etc. A lot of things and situations in your life are affected by this simple fact that water freezes so it’s nice that we have it at 0.

    Fahrenheit has 32°F …

      Well, it usually doesn’t actually start to freeze and snow at 32/0. It’s usually got to be below freezing for a while before it gets icy, and it’ll often snow above freezing and sleet below. It’s usually more dangerous if it’s above freezing because the layers of melting ice make the unmelted ice far more slick.

      It’s why for weather information, it really doesn’t matter what scale you use so much as knowing where those bands are on the scale you use.
      The peril is a gradient, so the actual number that matches freezing really doesn’t matter.

      At least that’s my take as a person who lives somewhere where cold weather conditions are a frequent topic of conversation.
      The temperature itself doesn’t start to get perilous until you’re in the negatives on the Fahrenheit scale, or -17C.

      The most I use in temperature is setting the air conditioner at work from 68 to 70 or 72 depending how hard I’m working

      Eh, it’s just exchanging what brain cells are used to remember what.

      With Fahrenheit you need brain cells to remember that 32°F is freezing point of water. With Celsius, you need brain cells to remember that 40°C+ is super hot outside.

        But, with Fahrenheit you also need brain cells to remember that 90F is super hot outside.

      And water boiling at 100C is useful too because boiling water is used so often in cooking.

        I gotta ask, do you use a thermometer to boil water?

        Metric is a more coherent system, but let’s not pretend it’s magic or more than it is.
        The numeric value associated with boiling water has no impact on cooking, because the boiling water doesn’t care.

          I gotta ask, do you use a thermometer to boil water?

          No, but I use a thermometer (built into the electric kettle) to prepare tea. Greens want to be brewed at 75-80C. Whites are often about 70C. Oolongs are about 95C.

          The numeric value associated with boiling water has no impact on cooking, because the boiling water doesn’t care.

          But the human who is doing the cooking might care.
