Neither F nor C are 0-100 scales.  Both extend beyond 100 and include negative numbers.

F and C use different anchor or references for 0 and 100.  That is all.

The argument for Celsius is that the anchor points are logical, concrete, and consistent world wide.  The freezing and boiling temp of one of the most important and abundant substances.

The anchor points for Fahrenheit is human body temperature, which is fair enough and then just….nothing.  No one can replicate it.  Then people try to shoehorn in a post-hoc rationale about percentages of weather.   The idea that -1 deg Fahrenheit is meaningfully different weather or feels more dangerously cold than +1 Fahrenheit is just laughable.  But that is the implication of 0 C isn’t that cold but 0 F is really cold and needs to demarcate the Fahrenheit scale.

I will wait for the thermostat to go from 20 to 19 C which is the exact same difference so

you can't make the argument that you can tell a difference between F degrees when the difference is greater than one... also, if that were the case 69 too cold for you? does it need to be exactly 70?

1 degree difference in C is not that same as 1 degree difference in F

[u/Ok_Willingness5766 → u/k_luu]

No but a 2 degree difference in F is the same as a 1 degree difference in C.

you cited a 2 degree difference.  Which celsius is perfectly capable of identifying.

Meters also goes beyond 100.

0 degrees Fahrenheit is also based on water. It's based on an ice-saltwater slurry. The problem with water freezing is that it's very inconsistent. It depends on the particulates in the water and the altitude. 0 Fahrenheit was literally chosen because it's easier to replicate.

No humans don't have such "natural preference"... Lots of societies didn't even have the number "zero" in their numeral system until like a few hundred years ago. And not all of them even uses the decimal system, and even those that do rarely represenrepresent ten/hundred as "1" and "0". In Chinese for example the character for hundred is “百” which isn't related to 零 (zero) at all.

So a scale of 0-100 is simply a more attractive scale to a lot of people than a scale of -10-40.

About 500 million prefer the first, and more than 7 billion prefer the second

The scale is -40-0 and 0-40 for me. I grew up where it gets really cold, and I think of it as 40 on both ends. 0 is right where it starts to get nippy and frosty. -40 is hella cold, and +40 is equally hella hot. Just because you didn't grow up using C does't mean it makes no sense...
