The conversion
74°F = 23.33°C
°C = (°F − 32) × 5/9, so (74 − 32) × 5/9 = 23.33.
As an outdoor air temperature, 74 °F sits in the mild 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
23.33 °C converts back to 74 °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.
