The driving distance between Abu Dhabi and Dubai is about 92 miles, while the air distance between the two cities is just slightly over 80 miles. There are 70 nautical miles between them.
Both cities are located along the Persian Gulf in The United Arab Emirates. The reason for the differences in mileage between the different modes of transportation between Abu Dhabi and Dubai is the routes that each form of transportation takes between the two cities. Geography makes it necessary for roads to twist and turn, creating greater traveling distance; planes typically travel in a straight line, as do boats. Nautical miles, however, are measured differently to the standard mile, which is why there are so many fewer nautical miles than either driving or air miles between the two cities.
