There does not seem to be a specific set of unit strings. Note
that doing:

In[1]:= UnitConvert[Quantity[12., "Feet"], "Meters"]

Out[1]= 3.6576 m

returns a result essentially immediately. But doing

In[2]:= UnitConvert[Quantity[12., "Foot"], "Meters"]

Out[2]= 3.6576 m

returns the same result after a small delay. You should see a
brief message indicating Mathematica is interpreting the units.
I believe what is happening here is Mathematica is using Wolfram
Alpha to interpret the unit string which increases the allowable
number of unit strings significantly and makes it essentially
impossible for a user to create a list of allowable unit strings.
