I adjust a thermostat regularly. 1C is way too large a swing, and I’ve stayed at hotels that offer half degree F adjustments.

Celsius doesn’t work well for human temperature. In America, air conditioning is common. Even poor people have air conditioning and often use it.

Come on, surely you don't believe your own argument. If thermostats can offer fractional-degree adjustment in fahrenheit, they can offer it in celsius.
