USA is called 미합중국 (미=America, 합중국=United States), or 아메리카 합중국. The latter is more formal. "America" the country is commonly called 미국 (미 stands for America - the "me" part, 국 is a suffix for "country"). It is also called simply 아메리카, which is the Korean spelling of the word "America". For example, North America is 북미(북=north) or 북아메리카, and the South 남미(남=south) or 남아메리카.
