Looks like you have got it.  In words as I read it, the River Yangtze has a
length which is a LengthMeasure whose transform is #LengthInKilometers  and
whose numerical value (the result of applying the transform, as we know, but
as RDF does not ) is 6300.  That is exactly the idea.

(And, as we also know, it might have other LengthMeasures as well).

This is interesting - using this pattern we could have an area whose width
is in one unit and whose length is in another. Very gratifying!
