"Long" is a term denoting the dimension being measured (i.e. length).
True. Irrelevant, but true. You still require a number and a unit in order to define a measurement.
What you are measuring (length in this case) is an entirely different matter.

Did you take 1st grade math with the plastic rulers at any point in your life?
Yes. And I took physics, and chemistry, and a host of other subjects where it was drilled into me that absent both units and numbers, you don't have a useful measurement of anything. Saying "I have 5" is meaningless. 5 what? Similarly, saying "That's miles away" is meaningless. How many miles? 2? 10? It can be anything. Surely you don't assume that when someone is in the "mile high club", that they must have been exactly one mile up in the air at the time, right? It's a label. Nothing more.
