The conversion
46°F = 7.78°C
°C = (°F − 32) × 5/9, so (46 − 32) × 5/9 = 7.78.
As an outdoor air temperature, 46 °F sits in the cold band. The other scale is on the dial beside it in the app, so a reading like this needs no conversion at all.

The other direction
7.78 °C converts back to 46 °F, which is the same relationship read the other way. Going from Celsius to Fahrenheit, multiply by 9/5 first and then add 32. Adding first is the usual mistake.
