Apple Watch total calories burned in one day

Is the "Move" category of Fitness on my AppleWatch designed to calculate all calories outside of my Basal Metabolic Rate?

For example if my fitness app says Move 870 Calories and my Basal Metabolic Rate from an inBody scan (body fat/muscle analysis) is 1700, then I could add the 1700 + 870 and get my approximate calories burned in one day?
