    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.
