A unit is the smallest whole increment of something.
In a math textbook, it might be a chapter or several chapters that cover one topic.
On a number line, it is the distance between 0 and 1.
A unit of measure can be something physical, as an inch or kilogram; or it can be something you have a hard time seeing, as a second or newton.
In business, a unit might be a single item you might count as inventory, a bathtub or a greeting card, for example. Such units are the basis of calculation of value and taxes.
