    This knowledge comes in handy with marketing BS around CPU coolers. If an aftermarket cooler gets a CPU to 35C when the stock cooler is at 70C, marketing will sometimes claim it cut temperatures in half.

      perhaps it cuts generated temperature in half, ie idle cpu is 50C, stock 70C, and aftermarket 60C

      I mean… that’s literally half though

        to make the argument even simpler, that phrase wouldn’t even mean the same thing to an english person as it would to an american.

        In fahrenheit those temps would convert to 95f and 158f.

          But °C was mentioned in the units, and its well understood that 0°C is a cold temperature for humans.

          I’m not a fan of marketing doublespeak either, but I think the right scale and right terminology was used here. They cut the temperature in half, in Celsius, on the basis that 0°C is very cold.

        If you convert those temperatures to Kelvin, they become 308K and 343K. Since Kelvin is absolute and we’re measuring the same material, this tells you how much more thermal energy is there and their actual proportion to each other.

          thanks, this makes a lot more sense.

          That being said, 70C down to 35C is a huge difference, relative to the temperature ranges we live in

        But it’s not.

        Celsius and Faernheit are interval scales, not rational scales. The absolute change from one number to the next is consistent, but since you can go into the negatives, 1 is not double 2.

        Kelvin and Rankine are rational because they use an absolute zero.
