Of course! You can chart in whichever temperature units you prefer. Simply tap the gear icon in the 'Temp' / 'Temp two' card on your data screen to make your choice.
All temperature readings are rounded to the nearest 0.05°C / 0.1°F when displayed on your chart. There's also the option to drop the final digit (truncated) if required by your charting method.
The temperature scales match up to allow educators to give you consistent support no matter which units you choose.
