The logarithm of a unit does not have significance.  Think of
what a logarithm is (for example, the logarithm of base 10):

If 10^x = a, then x is the logarithm of a.

If you look at it that way, it's not hard to tell that no matter
how many times you multiply 10 with itself, you won't get 100 meter.
