[iMore Question]

I don't know how I changed my setting to Celsius from Fahrenheit on weather.com.

I'd like to think there is a setting either at the website or via the app, if you're using an app. Being that I do not use either, I do not know. Anyway, while awaiting a response from someone who may be able to answer your question, I recommend you review the settings on weather dot com.
