How to measure the length

The metre is the unit of measurement for length.

But you can't measure everything in metres. Try to measure the length of a road. The number is too big! That is why multiples exist: decametre, hectometre and kilometre.

Now, try to measure the perimeter of a polygon.. do you need a metre? No, its submultiples are enough: decimetre, centimetre and millimetre.
