    Freezer normally operates at -4F

    You can’t survive without clothes at 55-60F, either.

    100F will not burn you in an instant, but the comment went into long-term survival, and good luck surviving at that.

      Not sure where you got -4F from.

      USDA, United States Department of Agriculture, recommends 0°F or -17.8°C

      100°F in the shade isn’t extreme, and you’d be able to survive normally (With more water, everyone can use more water)

      100°F is hot tub water

      120°F is recommended hot tap water

      140°F water will pretty much burn you instantly

          90-110 is hand washing temp. 100 average.

          110 is hot

          120 recommend max

          130 very hot

          140 very very hot

          150 burns

          If I said to you. Would you stick your hand in 50°C water for 100 dollars would you do it?

          What about 60°C?

          65°C?

          I bet you don’t know what would happen if you stuck your hand in 65°C water without looking it up. There’s a huge jump from 60° to 65°C. 70°C will instantly scald you.

          Someone out there is stupid enough to think. Water boils at 100°C, 65 should be perfectly fine. Even though water doesn’t boil until 212°, most people would be cautious of sticking their hand in 100°F+ water.

          Yes if you think 40°C+ is hot then you can gather that 65°C would be hotter. But why compare to 40° when you can do 100°.

        Guess what, Canada sets the freezer at -15 Celsius. The USDA just chose 0F because it’s good enough and a nice easy to remember number, there is nothing special about it.

        Same with all your other numbers, your just using whatever the closest even F value is that’s easy to remember there’s nothing special about any of them and we have equivalents in Celsius

          your freezer at -18 °C (0 °F) or lower. This will keep your food out of the temperature danger zone between 4 °C (40 °F) to 60 °C (140 °F) where bacteria can grow quickly.

          According to Canada.ca

          Every 2 F is basically 1 C. You have more whole numbers with F.

          Like -15°C is 5°F

          6°F is -14.4444°C

          -14°C is 6.8°F

          So 5, 6, and 7°F are about equal to -15, -14.5, and -14°C.

          And it’s not just a random number. You know how much more energy would be used if everyone kept their freezer just a couple degrees colder? It’s the optimum recommended temperature.
