It sure can! This can be set within the Kinsa app for Smart Stick and Smart Ear readings. You can also set this manually for the Ear display.
To change the units displayed in the Kinsa app:
- Open the app.
- For iOS, tap on More > Settings (or just Settings). For Android, tap on menu (upper left) > Settings (or just Settings).
Here you can switch the units between Fahrenheit and Celsius. All temperature readings (prior and future) will automatically convert to your new setting.
To change the units displayed on the Smart Ear itself:
- From the back of the thermometer, push down on the bottom half and slide it down.
- Remove the batteries.
- There is a small switch underneath labeled C and F. Flip to your desired units.
- Replace the batteries, and take temperatures normally.
Note that units displayed on the Ear for each reading will match your manual setting, but units displayed in the app will match what you selected in the app Settings (e.g. Fo may display on the Ear while Co displays in the app).
