We’re taught both metric and US customary units in school. I prefer metric for most things, to the point I have a metric-only tape measure among other things.
However, I’ll die on the hill that Fahrenheit is superior for ambient air temperature. 0 degrees to 100 degrees neatly encompasses the range of average surface temperatures seen throughout the year in the contiguous US.


Celsius does seem like a horrible measurement for weather.
Otherwise, metric is the clearly the best, but it’s foreign to me. I honestly have no idea what 175 cm looks like, or how heavy 5 kg is.
What is wrong with celsius?
There’s only about 30° difference between freezing and unbearably hot. Doesn’t seem accurate enough.
Accurate? It’s accurate; 0º water freezes. 100º water boils. 40º weather is hot AF. 40º and humid, is miserable.
Sure, for science, it’s brilliant. In the real world nobody really cares about anything beyond halfway to boiling.
Under 40, bundle up
40s wear a coat.
50s jacket
60s hoodie
70s indoor clothes
80s as little as possible
90s naked
Vs.
4-10 wear a coat
10-15 jacket
15.6-20.5 hoodie
21.1 -26.1 indoor clothes
26.6-32.2 as little as possible
Over 32.2 naked
I didn’t have to add decimals to any of the F values. There is no noticeable difference at half a degree fahrenheit.
They probably just aren’t familiar. I’m not. I like the idea of 0-100F being what humans can safely and directly experience (+/-30) but I have plenty of contacts that intrinsically know what C means to the same degree.
Where I live, in southern Europe, we get 40ºC several days a year (104ºF), and the odd 40 to 45ºC (113ºF). Thankfully dry. If humidity is low, and you have water and shadow, know how to dress, and you are reasonably healthy, 100 to 113ºF are safe, albeit not comfortable. People do live in Arizona, no?
Yeah, that’s what I’m saying. It’s roughly the range, not an exact definition. More humidity, laboring to survive, or not having modern access to water would make 100+ considerably dangerous. Similarly, not having shelter, having high wind, or being wet makes 0- considerably dangerous. So yes, with current tech and convenience, we can casually survive -20 to 120, but it’s still pretty awful.
I was also saying the range in regards to what we can touch and perceive. I know 1000 is very hot and melts some metals, but I can’t really touch a 200 degree pot of water, either. I don’t have intrinsic knowledge of the difference.
The thing is that Fahrenheit is basically arbitrary. From what I read in Wikipedia, 0 is the temperature of some harebrained brine solution, and 100 the approximate temperature of the human body.
Temperatures may make more sense to you because of habit, but the references are nonsensical.
Knowing that 0 is where water freezes, and that 100 is where water boils, is a way more useful reference in general.
I know that 18 is a baseline comfort temperature, 30 is nice hot weather, anything above 38 is damn hot. normal body temp around 37…
We usually remember reference temperatures in whatever scale we use, but the basis of Centigrade seems way more logical to me.
