Seems like the right thing to do is 

   -surveyfoot              british-ft
   +surveyfoot              1200|3937 meter

   -geodeticfoot            british-ft
   +geodeticfoot            surveyfoot

and kill off "british", unless anyone can think of a reason to keep
this name for almost-but-not-quite-1.

Note that we have

    inch                    2.54 cm

which is exactly equivalent to 0.3048 meters per foot.
