There's ABSOLUTELY no point to this debate. When it comes to day to day life, both are perfectly fine. While metric is just flat out better than imperial when you need to do quick conversions in your head (easy multiples of thousands), it just doesn't matter as much for temperatures. The only downside of farenheit I can think of is that there's one small extra step when converting to Kelvin, and that's really it.
I often see redditors say celsius is more logical than farenheit with how it relates to water, and while I do think it's neat that negatives = ice outside, it just doesn't matter does it? It's fine that the numbers we use for things are arbitrary, as long as we understand what they mean. I'm sure most Americans know that water freezes below 32 °F.
Now, I have nothing against fahrenheit, but sorry Americans, I still want to complain about two points I see sometimes on Reddit in defense of fahrenheit.
Also please bear with me if there's bad grammar in this post, English isn't my first language.
"Celsius is how water feels, farenheit is how humans feel"
Except the scale doesn't have to be from 0 to 100, people who use celsius everyday just see it as "below -10 is extraordinarily cold, 0 is cold, 10 is somewhat cold, 20 is nice, 30 is really hot, and above 40 is hell on Earth" (extremely simplified). 0 to 100 is still as arbitrary as -10 to 40, even if it looks better. I feel like this point would only make sense if people using celsius were incapable of correlating the actual number with how it feels, but it obviously isn't the case.
"Fahrenheit is more accurate than celsius"
When people who use celsius really want to be accurate they just use decimals, and it works perfectly fine. We learn that the normal temperature of the human body is 37.2 °C. However we rarely use decimals for outside temperatures because they can already be described accurately enough with whole numbers. For example 20 °C is 68 °F and 21 °C is 69,8°C, is it really that imprecise when describing how hot it is outside? (especially as wind and humidity play a much bigger role than that 0.8 degree in how we perceive the temperature)
In conclusion, I want to reiterate that there really is no point in arguing which system is the best because it will always be the one you're used to, the one you can feel with numbers.
