Originally a word used to describe objects or matters that are visible to the naked eye. Also called macro or macroscopic. Macroscopic is usually used to describe the properties and phenomena of objects made up of many molecules and atoms without going into the behavior of the individual components. The microscopic method is the use of statistical mechanics to derive the macroscopic properties of an object from the properties and behavior of its components. In a more expanded sense, the term macroscopic is also used when the emphasis is on the overall properties and behavior of a system made up of many elements. It is the opposite of microscopic.

本来は肉眼で見える大きさの物や事柄を形容する言葉。マクロまたはマクロスコピックともいう。通常は多数の分子や原子から成る物体の性質や現象について,個々の構成要素の挙動に立入ることなく記述するときを巨視的という。構成要素の性質と挙動から統計力学を用いて物体の巨視的性質を導き出すのを微視的方法という。さらに拡張した意味で,多数の要素から構成される体系の全体的な性質や行動に重点をおくときにも巨視的という。微視的の反対語である。
