macroscopic

 
   
On a scale comparable with everyday objects and events. Thus a 1 kg mass or a 1 m rule is a macroscopic object, whereas an atom or an electron is not. Temperature is a macroscopic quantity (and is meaningless for a very small system), whereas spin angular momentum is not. Macroscopic properties can usually be well approximated by a classical treatment of a system, whereas quantum mechanics is often necessary to predict microscopic properties.
