title_body: When evaluating the weight of a multirotor, is there a standard way that the components are grouped?
upvoted_answer: To me the only weight that matters is the total weight of the craft that is airborne.  Or commonly referred to as All Up Weight (AUW).  That is what performance depends on.  That is what regulations are based on ( mostly ).  Anything else is just the weight of individual components in my opinion.
