I very much doubt a celcius thermometer would be calibrated in farheneigt in a country where people don’t use this metric, but you gotta convince yourself I guess.
Then you don’t know how to calibrate thermometers.
You can’t use boiling or freezing water. The boiling and freezing point of water changes based on pressure.
Any mixture of liquid water, frozen water, and ammonium hydroxide is 0°F at any pressure (assuming it itself isn’t boiling or freezing), which you can then calibrate to STP with a bit of math.
You’d half to take elevation into account. It’s 100°C at sea level.
For every ~150m (500ft) you go up in elevation, you should expect the boiling temperature to be about 0.5°C less.
Because 0°F to 100°F is way more reasonable for telling comfort than -17.78°C to 37.78°C
There is nothing more reasonable about F in that scenario. You like it because you are familiar with it, that’s it. I can assure you that celsius is perfectly reasonable for telling you the room temperature. Billions of people use it without any problems, decimals and all (which is apparently something that Americans find extremely scary).
I am not sure about this comfort thing you talk about.
Where does this come from?
Just wondering where does those numbers come from.
In any case I wouldn’t consider minus 0C on my comfort zone but that’s another topic…
100°F (37.8°C) is universally uncomfortably hot
0°F (-17.8°C) is universally uncomfortably cold. 50°F is exactly what you’d expect it to be, 10°C, and room temp is ~70°F (21.1°C). Honestly it makes a lot of sense compared to humans (and most mammals).
People exist in both extremes but there’s virtually nobody that could survive constantly in either temperature without taking measures and I’m willing to assert that as fact. Both are extreme but common. Thus I’m willing to call them a good general measure.
It absolutely doesn’t make any sense! 38°C is a heat wave where I live and it’s a hot place, and - 10 is never reached in most places in my country. Besides, you can get a thermometer between - 30 and +50 and you’ll have all temperatures you need. 0 is freezing cold, 21 is comfort room, and 25 is when the chocolate starts to melt in your fingers.
I could turn this around and say there is no sple way to tell -20°C oder +40°C in F.
Who decides that the F Values are the exact points where humans feel uncomfortable when it can be some nearby C ones?
When I’m doing things that require precision: grams and °C
When I’m telling how the room or the temp outside is, °F
Why? Because 0°F to 100°F is way more reasonable for telling comfort than -17.78°C to 37.78°C
It’s not that hard to use both and anyone incapable of doing so is an idiot.
Me, omw to do a little trolling by using Kelvin instead
What’s really funny? All thermometers are calibrated using 0°F
Add ammonium hydroxide to ice water and the mixture will always be 0°F. Everyone calibrates their thermometer this way.

Interesting! I bet you need a second point for calibration though. It would be funny if it was boiling water, i.e. 100°C.

American here. A ⅓lb burger is smaller than a ¼lb because 3 is less than 4 something something metric system.

I got it, just asking where the numbers come from.
Well, 0°F comes from the temperature of any mixture of ice, water, and ammonium hydroxide. 100, idk, but I’m guessing Fahrenheit had an upper bound.
Either way, he made a scale that said, for people, “really cold” to “really hot” and it is pretty instinctual to me.
Sorry I meant the comfortable temperatures. That I am not clear how is decided 😅 or who decided those values.

For someone that grew up using Fahrenheit, maybe. I have no desire nor need to learn it.
