How does Apple Watch calculate calories burned?

Jimmy Westenberg / Android Authority

When you set up your Apple Watch for the first time, you’ll be asked to enter your age, gender, weight, and height. Meanwhile, the device itself is equipped with various sensors to actively track your activity and heart rate. Through a series of algorithms, Apple uses this data to make a relatively accurate estimate of how many calories you’re burning.

Additionally, your Apple Watch allows you to specify your activities for better accuracy during workouts. Choosing a relevant type of workout (like outdoor cycling, for example) enables your Apple Watch to use the appropriate sensors and data sources when estimating results. This results in a specific calorie count for each workout type.

However, Apple Watches are powerful devices and these estimates are considered largely reliable.
