Or is it just more familiar? We all like what we're accustomed to. Is there some reason Celsius 'makes sense'? Why does it make sense that 22 is comfortable but 40 is miserably hot? It doesn't make any more sense than 72 and 100.
I grew up during the transition period I was too young to know Fahrenheit, I had just entered school when the switch was occurring.
My parents are pretty well used to Celsius now but still may occasionally use Fahrenheit such as some electronic device that allows F or C they choose F.
It's still a but messed up though since Canada borders the US. The old joke being weather reports that show the border with the US say Detroit shown as 90 and Windsor as 32 "See Marge as soon as you cross the border into Canada it goes dow to 32!"
But still you get people of all ages saying things like "300km/h wow that's nearly 200 mph" or "You weigh 70kg what's that like 150 pounds?". It's more due to history and the influence of the US on our culture, I bet more french speaking areas like Quebec, northern NB don't do that but who knows maybe they do.
Between +20 and +50 I'm still more comfortable with 70F-120F. I also spent some time in Illinois, where I learned to understand the subzero range from -15F to 0F.
At LOX temperatures of 90K and below, I'm most comfortable in Kelvin. ;)
-30°C and below - very cold weather +30°C and above - very hot weather
A <5% error for the zone that >99% of humans inhabit seems pretty practical to me. The freezing point is effectively identical.
Of course if you have a tool to accurately measure halves, then you can also measure any other division you care to use.
Freezing point of water: 32°F Average human body temperature (oral): 98.2°F
So that's 66.2°F, not 64°F.
Those two temperatures were the original reference points for the Fahrenheit scale, and body temperature was defined as 96°.
The current definition is relative to the melting point of ice (32°F), and the boiling point of water at standard atmospheric pressure (212°F, which is exactly 180°F higher than the freezing point). Except now body temperature is 98.2°F instead of 96°.
If you want a thermometer calibrated in Fahrenheit, you have exactly the same problem as you do with Celsius. You just have to put 178 markings between the two reference points, rather than 98.
People generally start sunbathing, wearing T-shirts and flip-flops, when the temperature goes above 10C here...
