Revit Lookup Table Acceptable Units - Consolidated List? / Units for ##NUMBER?

While the Autodesk help wiki calls out the acceptable parameter types for use in a lookup table, it doesn't list the acceptable units for anything beyond the example of "TotalArea##AREA##INCHES".
Does anyone know of a consolidated listing of all the acceptable units usable with each parameter type? My searches have proven fruitless.
I'm specifically trying to find a unit to use with a number, allowing a model number to be the lookup value. I understand that I could just call it "##LENGTH##INCHES", but I'd prefer to not kludge it, if a more appropriate way exists.
Thank you in advance for any help offered.

In case of doubt, let Revit do it for you. Create a parameter in a family, as usual. Then, use Export > Family Types. Revit will create a .txt file for you, with the proper syntax.
For example, for a parameter named as "MyNumber", which is of the "number" data type, Revit will create it as MyNumber##OTHER##

Brilliant idea! Thank you, Alfredo.
