Maybe this will help you...
I used the Field Calculator to convert a short integer field containing inches to a new text field containing feet and inches. So, for example, the value 126 from the integer field would then be 10' 6" in the text field.
str(!MAXWIDTH_SHORT! /12) + "'" + " " + str(!MAXWIDTH_SHORT!%12) + "''"
Where !MAXWIDTH_SHORT! is the short integer field. "/" returns the whole number (feet), while "%" returns the remainder (inches).
