Fahrenheit and Celsius labels for the main temp display

I’d like to see the temperature, at least at the very top of the display, the summary, LABELED so my US and overseas/Canadian viewers know what they are looking at. a simple 'F or 'C would be fine. We can all convert IF we know what we’re looking at.
Both would be great, but understand space limitations.
In what scientific world to we post data without a unit of measure?!?
