0112/2///62720#UAB065Nautical Mile (en)
定义
- A unit of distance used primarily at sea and in aviation. The nautical mile is defined to be the average distance on the Earth's surface represented by one minute of latitude. In 1929 an international conference in Monaco redefined the nautical mile to be exactly 1852 meters or 6076.115 49 feet, a distance known as the international nautical mile. The international nautical mile equals about 1.1508 statute miles. There are usually 3 nautical miles in a league. The unit is designed to equal 1/60 degree, although actual degrees of latitude vary from about 59.7 to 60.3 nautical miles. (Note: using data from the Geodetic Reference System 1980, the "true" length of a nautical mile would be 1852.216 meters.)
