Convert from quadrant to microinch

Unit Definition (quadrant)
The quadrant is 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 (6213.71 miles). The actual meter comes close to the design. Using the conventional figures of 12 756 kilometers for the equatorial diameter of the earth and 12 714 kilometers for the polar diameter, and assuming the earth to have elliptic cross section, the length of the quadrant is about 10 001 300 meters (6214.52 miles). In principle, the quadrant is divided into 5400 nautical miles; in fact, 5400 international nautical miles equal 10 000 800 meters.

Unit Definition (microinch)
The microinch is a common imperial unit of distance equal to one millionth of an inch, or 25.4 nanometers (nm). The microinch is used for precise machining tolerances and also to describe the roughness of surfaces.
