Shreyas - according to strcat, for _ character array inputs, strcat removes trailing ASCII white-space characters: space, tab, vertical tab, newline, carriage return, and form feed_. So your space is being removed by this function.

Just use the square brackets for the string concatenation. For example, your callbacks can be simplified to

 function h_Callback(hObject, eventdata, handles)
 str = get(handles.text1,'String');
 set(handles.text1,'String',[str 'h']);
 function space_Callback(hObject, eventdata, handles)
 str = get(handles.text1,'String');
 set(handles.text1,'String',[str ' ']);

Try the above and see what happens!

What you need to remember is that you are getting a string, not a number. If you want to use it as a number, you must convert from a string to a number. Then if you want to use the result as a string you need to convert from a number to a string.

screen = str2double(get(handles.text1, 'String'));  
screen = (screen*2.54);
set( handles.text1, 'String', num2str(screen))
