What makes 0F (-18C) special? How do you estimate survivability at such temperature? If I’d be out on the street naked, I would die there in a matter of minutes. At the same time, there is plenty of places where winter temperatures go -40F (-40C) and even below, yet people very much survive and live there.
Similar with 100F (38C). There are places with higher temps in the summer, up to 120F (49C) in some places, yet people survive. Still, if you’re not equipped with anything, 100F (38C) will burn you alive.
All that not to mention that 50F (10C) is actually cold, not comfortable.
Fahrenheit is only intuitive and “feeling-descriptive” because you’re used to it. From a person born in Celsius country, it’s really not less intuitive.
I know I can be comfortable in my birthday suit at around 25C. Less than 20 is chilly, less than 10 - cold, less than 0 - freezing. More than 30 is hot, more than 40 is deadly.
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.
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.
No it doesn’t, unfortunately.

0F is the temperature a freezer needs to be to keep food fresh.
50F is the point that you can’t survive without clothes, your body will not generate enough heat.
100F (38C) will not burn you alive. You can survive for a long time in a sauna at 200F.
100F is perfect hot tub 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
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

According to Canada.ca
Every 2 F is basically 1 C. You have more whole numbers with F.
