Units explained
Square Pole
A square pole is identical to a square rod, equal to approximately 25.293 m². 'Pole' is a regional name used in some US and British contexts.
Identical to square rod and square perch; differs only in regional naming preference.
Square poles appear in some historical US land records, particularly in mid-Atlantic states with strong English colonial heritage.

Square Rod
A square rod is an imperial unit of area equal to approximately 25.293 m². It is part of the historical English land survey system.
Derived by squaring the rod (16.5 feet or 1/4 chain). The rod, perch, and pole are three names for the same length.
Square rods appear in historical English and American land surveys and legacy property records. The unit is largely obsolete today, surviving mainly in legal descriptions of older land grants.
Standardized via the 1959 International Yard and Pound Agreement.
