For weather, the scale is arbitrary and there is no technical benefit to having Fahrenheit over Celsius, or vice versa. People like myself who grew up with Celsius find Fahrenheight to be crazy and difficult to work with. People like yourself find the opposite.
However, having a temperature scale which, at one end, roughly approximates the core body temperature of a human, and at the other, being the coldest attainable temperature of ice water and salt mixture really has no benefit whatsoever. I've heard the argument about F being "more precise" than C because the magnitude of 1 F in nearly half that of 1 C. But it's bogus for several reasons.
1. It completely ignores how well the human body senses temperature.
We can roughly feel a change in temperature of about 1 C, and so for weather, having a scale more precise than that isn't really that useful. But even so, many modern digital thermostats support increments of 0.1 C anyway, which is more than enough precision.
2. It ignores how weather reports determine and report temperature
The temperature can change by several degrees between where you are and where the weather station recorded or estimated the temperature. Weather reports usually give relatively large temperature ranges for a given period, usually a day, or when stating only a single value, they state an approximate extreme for each region.
3. The "degrees of frost" measurement sometimes used in the US is based on the concept of degrees below freezing point of water, 32 F. That is a completely unnecessary concept when using Celsius because the freezing point is simply 0.
There are many applications in which the relationship to water is useful. Cooking, for one. Water is used a lot and having the temperature at which you cook things relate to water is extremely useful. If you want something cooked at 100C, then putting it in boiling water is fine. Other times, if you want something at, say 80 or 90 C, then you know that if it starts to boil, it's too hot. On the opposite end of the spectrum, you know you don't want things in your fridge to be frozen, so you want to ensure that it doesn't go below zero.
As a convenience, the temperature at which people can stand to touch relatively comfortably is around about half way up the scale, somewhere around 50C, give or take a few degrees. Hotter than that starts to get really uncomfortable and over 60C starts to burn quite quickly.
Another clear advantage is that if the entire world was using a single, common temperature scale for everyday use, regardless of which that was, it would mean far less need for conversion when communicating internationally. As an Australian, it is really annoying when searching for various things in English, only to find that so many sources are aimed at Americans with any stated temperatures published in Fahrenheit, which I then need to convert. Sometimes, it's not even clear what scale that's being used and I have to figure it out based on other information. Conversely, if an American finds some temperature they need to know published in Celsius, they would also likely want to convert it too, which annoying and time consuming.
As an example, looking up information about how to temper chocolate. A lot of the information is published with values in F. You need to know 3 separate temperatures for the process, and having to convert them to C and remember the new values is very time consuming and confusing.
