My Apple Watch has been tracking calories burned during a workout and it (as well as the Activity app) showed around 600 active calories burned during a workout yesterday. However, the Health App is showing I burned 390 kcal. 390 kcal is not the kcal conversion of 600 calories. Why is this happening? Is there a way to change the units of a workout to calories the same way I can change the units of a walk from kilometers to miles?
