From the Honeywell website is the following
excerpt:
Why is it important to have
accuracy within 1�?
Most people sense a temperature change around 1.8�. Honeywell thermostats are more accurate than some electronic thermostats which can vary up to 9�. Most thermostat manufacturers use some of our thermostat technology - none are as accurate as Honeywell.

The 1.8� is 1.8�F. Note that this is
EXACTLY 1.0�C. Someone must have done research and found that the human
body can only distinguish a 1�C change. Thus a 1�F resolution or
"accuracy" is ficticious.
I wonder if people in metric countries rely on
thermometers as much as people in the US do. Maybe with people in metric
countries using the same system as their body's own thermostat and can get a
more accurate idea as to the ambient temperature without the use of a
thermometer. Fahrenheit is out of sync with the human body and thus using
the body to obtain a Fahreheit temperature is almost impossible, thus the need
for thermometers.

It may be because there are 9 0F to each 5 0C. Thus if one wants to change it up or down, usually one has to punch the up or down arrows twice. This may be because at most times 1 0C is equal to 2 0F (or you could say that usually each punch equals aproximately 0.5 0C.
