Seems I can find some definitions. Is that specific enough?
 
Macroscopic Variable A measurable quantity used to describe the gross state of the system. It depends collectively on the behavior of all the atoms and molecules. These are also referred to as thermodynamic variables. a macroscopic variable may be constant over time for a system, yet there will almost cetainly be continuous activity at the micro level.


anything else i can add...or does this make sense
 
Husky can you please tell me exactly were you quoted your definteion from.
Thanks
