Abstract: Uniqueness of the Carathéodory extension is proved for the unbounded case of Loeb's measure space construction in nonstandard analysis and these measures are studied. Methods are developed for handling sets in the -algebra generated by the internal sets. A quantitative theory of degrees of null measure is developed.
