No it doesn't, unfortunately.

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.

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

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
