I suggest you use

 iChoice = menu('Select a unit', 'inches', 'metres');

This will return 1 for inches and 2 for metres.

MATLAB: How to prompt a user to enter a string, then check that the entered string is one of the acceptable entries. If it is not, user must enter it again.

I think this is what you intended ...

unit = input('TEXT PROMPTING USER TO INPUT UNITS (EXAMPLE OF ACCEPTED UNITS (unit q, unit w, unit e, unit r) ', 's');
while not(strcmpi(unit, 'q') || strcmpi(unit, 'w') || strcmpi(unit, 'e') || strcmpi(unit, 'r'))
    unit = input('ERROR MESSAGE IF UNACCEPTED UNIT IS ENTERED (DISPLAYING ACCEPTED UNITS AGAIN: ', 's');
end

rather than checking that the value of unit was equal to that series of logical statements.
