Units have an idea to what they shall express.

The concept behind the term 'length' stems from common observations, we 
have as human beings, living on planet Earth:

The movement from one spot to the other requires a number of steps.

If we make '1 step' a unit, then the counting of steps would be 
sufficient to measure the distance between spot A und spot B upon the 
surface of Earth.

Now '1 Step' was not really useful, since all people have different legs 
and make different steps.

This problem was 'solved' by 'length of the King's feet'. Since England, 
Egypt, Prussia and the USA had different Emperors, the feet was 
different in different nations.

Then came Napoleon and replaced 'Royal feet' with 'the meter'.

This was defined by a Platinum bar in Paris.

Now smart Physicists came along, and wanted something more precise and 
not as expensive as that Platinum bar.

So they used light to define the meter, but oriented their definition on 
that Platinum bar in Paris.

With this light it and the definition of 'length' it was now possible to 
measure other distance, in directions, into which you cannot walk (like 
to the Moon).

But the concept was inherited from counting steps on a journey upon the 
surface of planet Earth, only generalised into other directions and 
measurement by other means than comparing length to the own limbs.
