Kvaliteediolemussuurus tähendab millegi eksisteerimist, eriti püsiva karakteristikuga. Objektile omistatud iseloomustus, nt objekti hind, ei ole selle objekti kvaliteediolemussuurus.
A quality characteristic means existing in something, especially as a permanent characteristic. A characteristic assigned to an object (e.g. the price of an object) is not a quality characteristic of that object.
