I mean, folks talk about how the smaller degree size in Fahrenheit is more convenient (like Ernest earlier in this thread). Except, one degree makes no difference either way. So it doesn't really matter.
Hah! Tell that to my thermostat. Partly it's because it's in the central hallway well away from all the windows, I have to adjust it constantly during the day. (What it needs setting to depends on time of day, how sunny it is, and the humidity,) It's not uncommon for one degree F to be the right adjustment and two degrees F (approx 1 degree C) to be too much.
Must be a Southern thing, then. I've only ever set my thermostat to one of two things: 70 degrees and off. It has always gotten the job done.
This house could really use a dehumidfier to keep the humidity constant. However, I never set the thermostat as low as 70. Today it was set to 80, which is fairly low because of the high humidity and clouds. On dry sunny days, I'll set it as high as 86.
That's 30 C.... if we did that here, the heater would be on for almost the entire year.
