The conversion

35°C = 95°F

°F = (°C × 9/5) + 32, so (35 × 9/5) + 32 = 95.

As an outdoor air temperature, 35 °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

95 °F converts back to 35 °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.
