How far is Ohio from Korea?

The question is ambiguous because Ohio is a landlocked state in the Midwestern region of the United States so the distance depends on which part of Korea the question concerns. The distance between Columbus, Ohio (the state capital) and Seoul, South Korea (the capital city of Korea) is about 6,939 miles

(11,167 km) by air in a straight line (as the crow flies). Distance may also be stated via travelable routes; either over water and/or on land.
