When do you use 0° and 100°C?
This is also at standard pressure and most do not live at sea level.
I don’t put a thermometer in my water to make sure it is boiling or one in my water to make sure it freezes.
It can snow and roads can ice before it hits 0°C
It has no real world applications
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°.
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
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
0-150 is the better range, and 75 is right in the middle. 100 is just a hot air temperature most people don’t want to be in but it’s not an extreme.
Saunas can get up to 200 degrees
Hot tubs are usually at 100
Freezers need to be at least 0
You say 15°C. 6° cooler than room temperature. But how much is 6°?
It’s 60°F.
50°F or 10°C is where you need clothes to survive
300, 325, 350 is where you bake cookies (149-176°C)
Fahrenheit has a bunch of 5 and 10s
Saying something like high 70s or low 70s for temp represents an easy way to tell temperature.
21° to 26° for celcius
I walk outside and say “It feels like high 70s today” someone using celcius would say, “Feels like 25°”. If it was a little warmer than “low 80s” compared to “Ehh about 26 or 27°C”
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.
