A unit is a collection of systems that form a stable part of a larger system (such as a city).
A unit itself could be thought of as a static system as it’s something fixed, making it an identifiable feature that defines something like a city.
Units are never stand-alone entities that aren’t either directly part of a system or a parameter: everything stands in relation to everything else.

In fact, I claim that whatever picture of the city someone has is defined precisely by the subsets he sees as units.
