Because of its scale, Fahrenheit works better for describing the temperature as it relates to people and how comfortable or dangerous it is. Celsius obviously works better for science and engineering. Both systems are arbitrary and either will work once your used to them obviously. Fahrenheit is anthrocentric. Celsius is centered around the phase changes of water at a standard (arbitrary) pressure. The only temperature scale that approaches universality and attempts to not be arbitrary is the Kelvin.

Fahrenheit is my preferred scale when dealing with weather and heating/cooling my home because with Fahrenheit, you can describe almost the entire range of normal human experience from freezing to death to burning to death with (almost always) only two digits and no sign change. If you see an extra digit or a negative sign on the Fahrenheit scale you know shit just got real. And as for the numbers in between 0-100, you can conceptualize them as a simple decimal range like we do for lots of other statistical things like movie ratings, school/exam grading brackets, political polls on TV, percentages, etc.
