centigon

(cgon)

   a unit of angle measure equal to 0.01 gon,0.01 grad, or 0.0001 right angle; this is equivalent to 0.009°, 0.54arcminute, or exactly 32.4 arcseconds. The centigon is useful in navigation(potentially, at least) because 1 centigon of latitude represents approximately1 kilometer on the earth's surface, in the same way that 1 nautical milerepresents approximately1 minute of latitude in traditional navigation.
