How do you measure?
You compare it to a thing, and then you count that thing. That's it!
How high you get while counting tells you how much -- how big, or how long, or how whatever -- it is.
By the way, that thing you compare it to has to be something you can count. Otherwise how could you count it at all?
What good is measuring? It changes the question "How much?", which you can't really figure out at all, to "How MANY?", which then you can use math and you CAN figure out!
And again to review: What is measuring? It is COMPARING put together with counting HOW MANY.
