> Sure, its clever that 0C is water freezing and 100C is water boiling, but most humans live only in a fraction of that range. So it forces all sorts of inelegant practical situations (notice how nearly every euro thermostat has decimals so you can set it to 17.5). Not exactly sure what you mean. Celsius is pretty convenient in ranges I care about. * -20 to +40 are outside temperatures here * 100 is Sauna temperature * ~100 is boiling temperature * 180-300 are baking/grilling temperatures The thermostat allowing .5 seems pretty reasonable to me. But what's the point in being able to change from 61 to 62 degree Fahrenheit on an AC? That thing is not even accurate enough to measure that.
