The conversion
48°C = 118.4°F
°F = (°C × 9/5) + 32, so (48 × 9/5) + 32 = 118.4.
As an outdoor air temperature, 48 °C 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
118.4 °F converts back to 48 °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.
