I don’t think you understand what I said.
Also, that’s a lot of explaining, and lots of feelings associated with arbitrary numbers. Fahrenheit doesn’t need anywhere near that level of explanation. It doesn’t necessitate the pegging of feelings to random numbers.
The sentence “Fahrenheit is a 0-100 scale of how hot it is outside” is all anyone needs to immediately understand and be able to use fahrenheit. I didn’t need to type out a long list of what each temperature value means to me. There is no need for a mneumonic such as “10 is cold, 20s not, 30s warm, and 40s hot”
If you’re doing math in a lab, absolutely use Celsius. I’m not saying it doesn’t have a place. It’s just not the be-all end-all most perfectest temperature measurement system ever.
I think you are projecting your feeling onto others; I don’t have “a mneumonic” in my head. That was for your benefit, since you are not immersed in that scale.
When I see the weather report and it says tomorrow it is going to be 25 degrees with light wind, I know that it will be a pleasant day. The same way I know what the reporter is saying, I have been immersed in the English language since birth, it requires no though to understand the words they are saying.
It requires no thought to understand that 25 degrees and light wind is a nice day. It just is.
I don’t have that intuitive sense for the F scale, I always have to convert it to a sensible number. I know 100 is around 37, which is really hot.
But it requires you to be familiar with an arbitrary -20 - 40 scale. Which makes way less sense than a 0-100 scale.
I don’t need to use the mnemonic either, I grew up in the U.S. so I understand both systems perfectly well. But the mnemonic exists because Celsius uses an inherently less sensible scale. You only understand it internally because you grew up with it. A person who grew up with neither system would find fahrenheit easier to understand from an unbiased position because it’s more logical.
deg C is no more arbitrary than deg F; any more than French is more arbitrary than English.
It is a strange argument to say “You only understand it internally because you grew up with it.”; well yes, but that is exactly the same with the deg F scale.
A person who grew up with neither system would find fahrenheit easier to understand from an unbiased position because it’s more logical.
In your opinion.
In my opinion it is far more logical to base you temperature scale on repeatable physical measurements, than say what a person feels.
0 C = water freezes
0 F =
Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt)
100 C = water boils
100 F = best estimate for average human body temperature.
The F scale is not built on logic.
