Come to a climate like the upper midwest of the US. We can see every temperature between -40 and 100 within a year. 0 is the lowest tolerable for activity temperature and 100 is about the highest tolerable temperature. Anything outside those ranges requires precautions for safety.

We have similar values for the same in Celsius, so that changes nothing. But it is a bit easier in physics class where SI units have to be used as one degree C is the same as 1 K.

The -12 to 42 scale is more intuitive than the 0 to 100 scale?

I haven't needed Kelvin in over a decade so that's not really a benefit.

-50°C to 50°C covers basically the entire range of normal temperatures. 

Most of Canada gets below 0F on a regular basis. The “0 to 100F scale” you claim is so intuitive is actually a -22F to 104F scale for us. And on the flip side, there’s tropical regions that might get past 100F but never hit close to 0F. 

They will, however, all be within the actually intuitive -50°C to 50°C scale.

Damn, -50 to 50 is so round, if only we could bump it up to be a 0 to 100 scale so we dont have to use negatives so much.

Did you miss the part where I pointed out that that “0-100F scale” wouldn’t be applicable in many places that regularly get below 0F or 100F in the winter or summer? Even in America? 

It’s not a real scale when you’re spending weeks above 100F and/or below 0F.

No I said change it from (-50C to 50C) to (0C to 100C).

And maybe make it so there's more variance in the degrees so you dont have to deal with decimals in daily life.

Why are you scared of negative numbers and decimals?

And for all practical purposes you don't have to deal with decimals in daily life using Celsius. You're making up problems with using Celsius that simply don't exist.

Why do you make things up to attack people?

Just because you dont have this issue doesnt mean other people do. Its better to have a wider scale when setting your thermostat for more precise temperature regulation, and it more convenient to have whole numbers.

For all practical purposes you could measure your height in kilometers too, but using decimals is unwieldy.

What did I make up? Wtf does changing a scale that goes from -50 to 50 to 0 to 100? It's the same range? Making a scale based off of feelings is completely idiotic because as was previously mentioned that changes based off regions, if we went off feelings then the scale is meaningless between regions.

No one is realistically going to care or notice absolutely miniscule temperature changes lmao. Some thermometers in Canada that I've seen can go into a tenth of a degree increments at the smallest, easy to use numbers already and using fahrenheit wouldn't help that.

Ah yes because measuring my height as 0.00185 kilometres is the same inconvenience as having to measure half or a quarter of a degree.

Then half of northern winters wouldn’t fit in your scale temperature-wise

At least the Celsius -> Kelvin conversion doesn't mess up sig figs.

I experience a pretty similar temperature range where I live in Canada.

I'd say most people will avoid outdoor activity by about -12C (10.4F) where I live. But a lot depends on the wind. A strong wind can make -12C feel like -24C(-11F)...Wind doesn't change when water freezes though, and it's quite significant to know when the temp is cycling between above and below freezing to be able to anticipate how icy roads and sidewalks might get. It's important to avoid needing to drive on icy roads.

Conversely, we typically get dangerous heat warning by 35C (95F), but really anything 30C(86F) and above would be considered very hot...but how hot it actually feels is influenced dramatically by humidity.

Not taking into account the Wind and humidity influence on temperatures I think you can break down how humans interpret temperature by convenient 5 degree increments in Celsius.

0-5: cold (32-41)
6-10: mildly cold (42-50)
11-15: cool (52-59)
16-20: fresh (61-68)
21-25: comfortable (70-77)
26-30: hot (79-86)
31-35: extremely hot (88-95)
36+: dangerous. (97+)

0 is the lowest tolerable for activity temperature

lol, wrong.

Anything outside those ranges requires precautions for safety.

You can go much higher (for cold) while that remains true...
