Steps to reproduce:
Search for "weather 75202" (Dallas, TX).
It shows "feels like 25 degrees" (celsius). I click to convert it to F, and it correctly shows 77 degrees.
Perform some other searches. Then do another weather search, it again defaults to celsius.
Dallas, TX is located within the US, which uses Fahrenheit.
Ideally, the weather report should show temperatures in the scale that is local to the area. If within the US, it should default to Fahrenheit.
The thing is, OK the first time I perform the search, it's moderately inconvenient to switch the format to Fahrenheit, but that isn't remembered. Meaning, that all future searches still default to celsius.
Maybe introduce an account setting for the preferred temperature "scale"?
