The "ut_unit" type is deliberately opaque: only the UDUNITS-2 library knows its 
structure. Consider this: what "value" would you expect from the celsius unit? 
How about a logarithmic unit?

So, you want to convert a bunch of (value, unit) pairs into (value', unit') 
pairs? Is that right? If so, then you should be able to do that by first 
obtaining a converter between the input and output units and then converting 
the value.
