Understanding Temperature Units on Smart Watches

Before diving into the steps, it’s helpful to understand how smart watches handle temperature data. Most smart watches don’t have built-in thermometers. Instead, they rely on weather data from connected smartphones or third-party apps like Weather, AccuWeather, or The Weather Channel. These apps pull information from online weather services and display it on your watch face or in dedicated widgets.
Because the temperature unit is often determined by regional settings or app preferences, it’s not always obvious how to change it. For example, if your phone is set to use metric units (common in Europe), your watch may default to Celsius—even if you prefer Fahrenheit. The good news is that nearly all major smart watch platforms allow you to override these defaults and choose your preferred unit.
It’s also worth noting that some smart watches display temperature in multiple places: on the watch face, in weather complications, in fitness apps during outdoor runs, and in health monitoring features (like sleep tracking, which may reference room temperature). Changing the system-wide unit setting usually updates all these displays, but occasionally you may need to adjust individual apps.
How to Change Temperature Units on Apple Watch
Apple Watch is one of the most popular smart watches, but it has a unique approach to temperature units. Unlike many other devices, you cannot change the temperature scale directly on the watch. Instead, you must use the paired iPhone and the Watch app. Here’s how to do it:
Step 1: Open the Watch App on Your iPhone
Unlock your iPhone and locate the Watch app—it has a white icon with a blue watch face. Tap to open it. This app serves as the central hub for managing your Apple Watch settings, including notifications, apps, and system preferences.
Step 2: Navigate to the General Settings
Once inside the Watch app, tap on the “My Watch” tab at the bottom left. Then, scroll down and select “General.” This section contains a variety of system-level options, including language, region, and units of measurement.
Step 3: Select “Units”
In the General menu, look for the “Units” option and tap it. Here, you’ll see a list of measurement categories: Temperature, Distance, Weight, and Volume. Each can be set independently, so you can use Fahrenheit for temperature while keeping kilometers for distance, if you prefer.
Step 4: Change Temperature to Fahrenheit
Tap on “Temperature” and select “Fahrenheit” from the list. The change is applied immediately. Your Apple Watch will now display all temperature readings—whether on the weather complication, in the Weather app, or during outdoor workouts—in Fahrenheit.
Step 5: Verify the Change on Your Watch
Go back to your Apple Watch and check the weather widget or open the Weather app. You should now see temperatures in Fahrenheit (e.g., 75°F instead of 24°C). If it hasn’t updated, try force-quitting the Weather app by pressing the Digital Crown to return to the home screen, then reopening it.
Pro Tip: If you frequently travel between countries that use different units, consider setting your iPhone’s region to a country that uses Fahrenheit (like the United States). This can help maintain consistency across all apps and services.
