It is never pleasant for humans to understand: a lot, a little, a little more and these things.  People like to know the scope of a thing more so that it is easier to imagine;  For example, you say: ((I drank a little water)) but the face of the other person is like a question mark, ((a little means how much?)). Now it is enough to say ((a cup)) everything will be solved, and the smile will satisfy the audience.  You see, In physics. For this pleasure and accurate measurement, we choose a special cup for each important entity we are talking about;  For time seconds, location meters, etc.  When you say ((I moved)) nothing can be done, and of course, it doesn't matter, but when he says ((I moved 5 meters, and it took 2 seconds)) that's when it is possible to play physics with you.  Let's say at least your speed, although it won't help you.  In short, these glasses are called units of measurement in physics.  The units that are accepted by all of the world, even almost all of the world, is also called SI units
