Garmin forerunner 945 Calories Count

Hi there . I bought a new Garmin forerunner 945 . However , it seems that the device under estimate the calories I burn . For example I am 6 and weights 226 pounds . I walked 4 km for 40 mins , but show as that I only burned 341 calories . When for example I use my Fitbit tracker it shows that I burn 435 calories for the same distance ! In my opinion I should have burned at least 420 calories for that type of exercise. Did anyone have the same experience as me ?

Sounds like fitbit may be including BMR calories in an activity while Garmin doesn't, just in the daily total.

Sometimes it is the activity class setting that makes a difference. Did you set it (there is a link to the setting vs activity hours in the post) ?

How can it change the calories count on an activity?

Garmin should include it .because BMR is still calories burned

I found somewhere that Garmin uses it to calculate calories, but no formula was mentioned.
