League is a measure of length in the inch-pound system of units customarily used in the United States. A statute league equals 3 survey miles. It also equals 15,840 survey feet, or 4.828 kilometers. A nautical league equals 3 international nautical miles. It also equals 18,228.346 international feet, or 5.556 kilometers.
The league dates to ancient times. The Gauls used a league equal to 1,500 Roman paces, or 2.22 kilometers. The Normans brought a league to England. At first, the English league equaled 2.4 kilometers, 11/2 times the length of the English mile. British and American sailors once used the nautical league. Today, they use the international nautical mile.
