The conversion
0°C = 32°F
°F = (°C × 9/5) + 32, so (0 × 9/5) + 32 = 32.
As an outdoor air temperature, 0 °C sits in the cold band. The other scale is on the dial beside it in the app, so a reading like this needs no conversion at all.

| 4 °C | 39.2 °F |
| 5 °C | 41 °F |
The other direction
32 °F converts back to 0 °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.
