This is a very good catch - and very interesting. Thanks for this post!
BTW: You tried everything except the 3_(m/2) version (this is the real "halfmeter") - the result is same.

I played a short time with decibel, because this is the only one unit which has no dimension (defined on the HP48xx as "1") - but after evaluating the result is alvays value_dB.

My opinion about the original question: this is a normal evaluation these type of objects: an unit object - for example in my engineering work - it has a value and it has a dimension. If the dimension has a value different from 1 as a multiplier, the unit's value must to multiply with this value and the multiplier of the dimension is remain 1 - in this rule based all the dimension conversion method:

25.4_mm = 25.4_((1/25.4)_in) = 1_in what is the problem with it?
