Quadrant (quad) 3


Quadrant (quad) 3 :

A unit of distance equal to the distance from the North Pole to the Equator. The metric system was originally designed to make this distance exactly 10 million meters. The actual meter comes close to the design, but it is a little short. In the Geodetic Reference System 1980 the value given for the quadrant is 10 001 965.7293 meters (6214.93337 miles). In principle, the quadrant is divided into 5400 nautical miles; in fact, 5400 international nautical miles equal 10 000 800 meters
