Celsius is as arbitrary as Fahrenheit. Really, it's the one unit where it does not matter. Meters, kilogram, seconds, volt, ampere... they all stand in relation to each other. Celsius doesn't, you'd have to go to Kelvin for that (which is derived from Celsius, but Celsius is still useless by itself). I'm European, grew up with Celsius and am therefore more comfortable with it, so hardly any bias there.
