Comment on temperature

  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

      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.

      The 120 and 140 don’t make that much sense unfortunately.

        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°.
