The conversion

97°F = 36.11°C

°C = (°F − 32) × 5/9, so (97 − 32) × 5/9 = 36.11.

As an outdoor air temperature, 97 °F sits in the hot 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

36.11 °C converts back to 97 °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.
