Hawaii
Hawaii ( hə-WY-ee; Hawaiian: Hawaiʻi [həˈvɐjʔi, həˈwɐjʔi]) is an island state of the United States, in the Pacific Ocean about 2,000 miles (3,200 km) southwest of the U.S. mainland. It is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics.
Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning 1,500 miles (2,400 km), the state is physiographically and ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the fourth-longest in the U.S., at about 750 miles (1,210 km).
