After moving to Europe I am completely on board with the simplicity of the metric system, however I do prefer the Fahrenheit scale for exactly the reason you described above.
A human will face winter weather conditions from 0-32F which converts to negative values on the Celsius scale (not practical).
On the other end of the spectrum for summer time conditions, there is a wider range of values to ascribe to changes in temperature from 60F-100F or approx 16-38C.
