What is Used to Calculate Calories on My Multi-Sport Watch?

Depending on what accessories are used with the watch, calories burned during a recorded activity will be calculated in the following order:

• Firstbeat - calculated using heart rate user profile data
  
• Power Meter - calculated using instantaneous power
• Fitness Equipment - calculated using ANT+ enabled fitness equipment
• Speed, Distance, and User Profile - calculated using speed, distance, and user profile data

The device will automatically choose the appropriate method. There will be slight variations depending on the method used.

NOTE:  Some older Garmin products feature New Leaf as a means to calculate calories burned. This feature would hold precedence over the below methods however Garmin no longer supports New Leaf profiles.
