The conversion
12°C = 53.6°F
°F = (°C × 9/5) + 32, so (12 × 9/5) + 32 = 53.6.
As an outdoor air temperature, 12 °C sits in the cool 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
53.6 °F converts back to 12 °C, which is the same relationship read the other way. Going from Fahrenheit to Celsius, subtract 32 first and then multiply by 5/9 — doing it in the other order is the usual mistake and produces a plausible-looking wrong answer.
The full converter handles any value, in either direction, including kelvin, and shows the formula as it works.
