Exploring the Accuracy of the Apple Watch Series 4 Altimeter

Share This:

The Apple Watch Series 4 has a new and improved altimeter that is sure to get outdoor enthusiasts, athletes, and adventurers excited. The altimeter measures altitude by using air pressure, which is helpful for tracking elevation changes durig hikes or climbs. The Series 4 also boasts an always-on display, so you can quickly and easily check your altitude without having to turn on the watch.

The altimeter is incredibly accurate; within 10 feet of the actual elevation in most cases. This accuracy makes it great for tracking your progress on long hikes or climbs, and even taking part in orienteering. It’s also useful for making sure you know your exact location while flying a drone or quadcopter.

The Apple Watch Series 4 also has an additional hardware upgrade in the form of a built-in compass. This allows the watch to determine direction as well as elevation; useful for navigation purposes outdoors or finding your way around unfamiliar cities. The compass also comes with a neat feature called “Compass Mode” which gives you an interactive view of your current heading with real-time updates when you change direction.

Overall, the Apple Watch Series 4’s altimeter makes it an ideal choice for those looking for a reliable way to track elevation changes in their outdoor activities and adventures. Its accuracy and ease of use make it a great choice for anyone looking to explore the great outdoors without having to worry about getting lost!

Does the Apple Watch 4 Have a Barometer?

Yes, the new Apple Watch 4 does have a barometer. This barometer is intended to track elevation changes during a workout, whether it’s outdoors or within a building. It can also be used to track air pressure over time for metrics like temperature, humidity, and precipitation. Additionally, the barometer is part of a suite of health-centric sensors included in the Apple Watch 4.

Does the Apple Watch Have an Altimeter?

Yes, the Apple Watch Series 6 and Apple Watch SE both feature a next-generation always-on altimeter. This feature allows the watch to measure changes in elevation and provide real-time elevation information.

Accuracy of Altimeter on Apple Watch

The accuracy of the altimeter on Apple Watch can vary depending on the environment and conditions. Generally, it is accurate within a range of about 10 meters but can be off by up to 5 meters in either direction. In certain conditions, such as walking on flat ground, it may read as much as 70-150 meters off, whch indicates it is not particularly reliable in these cases. Ultimately, the altimeter on Apple Watch should be used as a general guideline rather than a precise measurement tool.

Does the Apple Watch 5 Have an Altimeter?

Yes, the Apple Watch Series 5 does have an altimeter. This new feature allows you to measure your current altitude and elevation gain when hiking or running. The altimeter also works in conjunction with other sensors like the GPS and barometric pressure sensor to provide a more accurate measurement of your altitude. Additionally, this feature can also be used to track your flights of stairs climbed throughout the day.

Does the Apple Watch 4 Display Altitude?

Yes, the Apple Watch 4 can show you your altitude. To view your current altitude, open the built-in Compass app on your watch. Scroll with the Digital Crown to see your incline, elevation and coordinates in the innr ring of the compass. You’ll also be able to see a graph of your elevation as you move over time.

Sensors in the Apple Watch 4

The Apple Watch Series 4 is equipped with a variety of advanced sensors. These include an accelerometer and gyroscope to detect hard falls, an electrical heart rate sensor to measure heart rate, an ambient light sensor to adjust brightness, a barometric altimeter to measure relative elevation, and a microphone for communication and Siri. Additionally, the watch features a new ECG app that uses the electrical heart rate sensor in order to take an electrocardiogram (ECG).

Changing Apple Watch from Feet to Altimeter

To change your Apple Watch from feet to altimeter, you’ll need to take the followig steps:

1. Open the Apple Watch app on your iPhone and tap on the ‘My Watch’ tab at the bottom of the screen.

2. Scroll down and tap on ‘General’, then tap on ‘Language & Region’.

3. Tap on ‘Custom’ and select a region that uses metric or imperial units. For example, select USA for feet or U.K for metres.

4. Once you’ve selected a region, scroll down and tap on ‘Altimeter’. This will set your Apple Watch to use altimeter instead of feet.

5. Finally, tap on ‘Done’ at the top rigt corner of the screen to save your changes.

You shoud now be able to view altitude readings in metres (or feet) instead of feet when using your Apple watch!

Setting the Altimeter

You should set your altimeter to 31.00 “Hg. prior to reaching the lowest of any mandatory/crossing altitudes or 1,500 feet above ground level (AGL) when on a departure or missed approach. Air traffic control will issue actual altimeter settings and advise pilots to set 31.00 “Hg., however it is important to always check the latest altimeter setting before flying.

The Features of the Apple Watch Series 4

The Apple Watch Series 4 with watchOS 5 offers a wide range of features that make it a powerful device for staying connected, tracking your fitness goals and monitoring your health. It has an advanced activity tracking system that allows you to track your workouts and other physical activities, as well as keep tabs on your oveall fitness level. It also has a communications feature that allows you to stay in touch with family and friends via messages, phone calls or FaceTime.

In terms of health capabilities, the Series 4 Apple Watch is revolutionary. It comes equipped with a new accelerometer and gyroscope that are able to detect hard falls and an electrical heart rate sensor for taking an electrocardiogram (ECG) using the new ECG app. Plus, it can monitor your heart rate throughout the day and alert you if there are any irregularities in your rhythm. Finally, it can be used to detect noise levels that could potentially damage your hearing over time.


The Apple Watch Series 4’s altimeter has been found to be somewhat unreliable in terms of accuracy, with readings sometimes varying by as much as 150 meters. The addition of a compass and altimeter in the Series 5 has slightly improved accuracy, but users are still liely to experience some variation in readings. While it may not be suitable for serious navigation or tracking purposes, the Apple Watch Series 4’s altimeter can still provide useful information about elevation changes during a workout or other outdoor activity.
