Body Temperature - Thermometer supports a one-tap switch between Celsius and Fahrenheit. The current Google Play listing confirms the one-tap unit feature, and the official companion-app screen labels the temperature value with “Tap value to switch °C/°F.”
Changing the unit changes only how the same wrist skin-temperature reading is displayed. It does not change the sensor, the measurement site or the app's medical limitation.
How to change the temperature unit
- Open Body Temperature - Thermometer and find the temperature value in the interface provided by your installed version.
- On the companion-app interface shown in the official store image, tap the value labeled “Tap value to switch °C/°F.”
- Check the unit symbol beside the number to confirm the change.
Does switching units change the measurement?
No. Celsius and Fahrenheit are two ways of expressing temperature. Switching the unit changes the displayed scale, not the underlying wrist sensor reading.
This also means the unit switch does not convert wrist skin temperature into core body temperature. Samsung's sensor documentation describes skin temperature around the watch as different from body temperature, and the app listing says the product is not a medical device.
Which Galaxy Watch models are listed?
The current Google Play compatibility section names Galaxy Watch 5 and 5 Pro; Watch 6, 6 Classic and 6 Classic Astro Edition; Watch 7; Watch 8 and 8 Classic; and Watch Ultra and Ultra (2025).
The current listing specifically names Samsung Galaxy Watch models and does not name Pixel Watch or another non-Samsung model. Check live device eligibility on Google Play before installing.
Other quick-access options
The same listing says the app includes a Wear OS Tile for quick access and complication support for compatible watch faces. It also describes the watch app as standalone. Those features can make the wrist reading easier to reach, while the Celsius/Fahrenheit control changes how the value is shown.
Keep the reading in context
Body Temperature - Thermometer reports wrist skin temperature. Wrist skin temperature is not the same as oral or core temperature.
This app is not a medical device and is not intended to diagnose, treat, or prevent fever or any medical condition. Consult a healthcare professional for medical advice, diagnosis or treatment.
For the measurement context, read why wrist skin temperature differs from core temperature. The feature and compatibility overview explains the wider app listing.
Frequently asked questions
Can I change from Celsius to Fahrenheit with one tap?
Yes. The current listing describes a one-tap switch, and the official companion-app screen instructs users to tap the temperature value to switch °C/°F. Follow the interface in your installed version.
Will changing to Fahrenheit remeasure my temperature?
No. It changes the displayed unit for the reading; it does not perform a different kind of sensor measurement.
Is the displayed value core body temperature?
No. It is wrist skin temperature and must not be used to diagnose fever or illness.
Where can I check the current interface?
You can view Body Temperature - Thermometer on Google Play for the latest screenshots and app details.
