When writing a sentence that contains the short version of inches as a double quote, (e.g. the box measured 14") does the period come before, or after the quotation mark?
It comes after: the quote isn't being used for the purpose of quotation.
Actually, the abbreviation for inches is a double prime; even in the case you use the quotation mark as abbreviation, the period is placed after the abbreviation.
I am 6′2″.
I am 6'2".
