1. A unit of area, nominally six miles on a side. It is subdivided into 36 sections, numbered as shown in Figure T-11. 2. A designation of an east-west row of townships. American townships are specified in relation to standard reference parallels (which often are not stated explicitly); T3N indicates a township in the third row north of a reference parallel. Canadian townships are counted northward from the 49th parallel. See also range.
