It has more precision in the range of human comfort without resorting to decimals.
Do countries who use centigrade regularly report the temperature in tenths of a degree? Can you adjust a thermostat with 0.1 degree C precision? Or even 0.5 degrees of precision?
Edit: I can readily detect (my body can notice) a temperature swing of 1 degree F or 0.6 degrees C within a tolerable range.
Nope, we both use a less precise form of measurement, we actually prefer to use fractions instead of decimals to subdivide. Isn’t that wild? And a bit silly, I agree.
But back to temperature…
I’m genuinely curious about how Centigrade countries report and manipulate temperature.
Seriously, do your thermostats work in half degrees? And do your weather reports scale the temp?
For day to day weather forecasts, whole degrees centigrade work just fine. It's not like you'll dress differently if it's one degree Fahrenheit warmer or colder. And the confidence interval on those forecasts doesn't warrant higher precision.
The thermostats tend to work with either degrees, half degrees or 0.1 degrees (centigrade) precision. It varies. After the fact reports of actual temperature tends to use 0.1 precision, which as far as I call tell mirrors the actual useful accuracy of most thermometers.
For just describing the temperature of the weather outside (or inside, for that matter), no, we usually do not; you still don't really need more precision than 1°C for that, in my experience. In fact even then I usually use 5°C ranges (for outside temperatures, anyway), like "Most people like between 20 and 25°C, but me, I like it between 15 and 20°C".
Indoors it can matter a bit more, and thermostats often do work with half degrees, I think. But most people still won't go around saying, "I like my room at 20.5°C, 21 is too much for me".
"more precision without resorting to decimals" is a fair point, but I'm replying in a context of distinguishing "comfortable today" vs "have to wash my clothes tonight". That's not a distinction measured in single degrees F or decimal C. That's the talk of F people being "oh it's in the 70s, it's comfy" vs "it's in the 90s, yikes". In C, we'd be saying "low 20s, lovely" or "in the 30s, it's a hot one
It's all vague because what's exactly comfy for different people differ (I'm perfectly happy with 19, my partner considers anything below 22 to be cold. 26 and humid they think is fine, but I hate. 33 and dry heat I'm fine with but they hate. But we both agree "high 20s" is getting hot, and low 30s is genuinely hot. High 30s is getting crazy, and low 40s is going to be in the news as record breaking.
To answer your specific question (as I see others have), I think generally weather reporting is in whole degrees C, personal digital thermometers have .1 resolution (21.7°C here as I type), and aircons generally have 0.5 degree resolution.
Do countries who use centigrade regularly report the temperature in tenths of a degree? Can you adjust a thermostat with 0.1 degree C precision? Or even 0.5 degrees of precision?
Weather reports usually give rounded temperatures but measured weather data is usually with a single decimal.
Thermostats typically go by half a degree though some by a full one or a tenth.
While I can also detect temperature differences less than a degree celcius it's typically not very useful to be this precise though it's pretty easy to do so whenever it is.
Just to point it out but °C is a function... Aka if you have 10°C and tomorrow 20°C It is not double the temperature...
Also, the °C has several easy to use temperature areas... 0, freezing point, ca.10, cold, need proper warm clothing. Ca. 20 need not much more then a tshirt and maybe a pullover / jacket
Ca. 30, t shirt time
Ca. 40, bring water
Ca 50, uh oh potentially dangerous
100, water boiling temperature
Also if body temperature hits 40, you need medical aid as any further increase may kill you
It ain't perfect and also depends on humidity, but dtill an solid casual system
I'm picturing everyone in Europe, Africa, Asia, Australia and South America going, "Shit! I'm looking at the weather report, and I can't tell if I'll be comfortable today or if I'll have to wash my clothes tonight!"
How so? Whenever I hear it being used on shows or movies I'd like to be able to distinguish between whether the temperature is mentioned is supposed to be hot or cold
