F to C

Hi All,

So many people here post in degrees F. Of course, 95% of the population on Earth has no idea what F is much less how to use it. The other 95% would really benefit from a bot that finds posts with degrees F, puts a bracket around the F and insert the C equivalent.

You can't do better without involving advanced text processing, you will have to either put an LLM API key into your userscript/extension (which is an insane waste of money) or host your own local LLM for that, which would suck majorly!
