The technical term for a 10 km map square is a Hectad.

When this 10 km square is divided into a grid 10 by 10 it gives the next size of grid square. This unit is called a Monad and measures 1km square. 100 monads fit in a 10km square.

Out of the monads generated from square SD23, 322 are land and -222 are sea. Sea squares are disregarded on this site as they contain no land features.
