Units explained
Square Yard
A square yard is an imperial unit of area equal to exactly 0.83612736 m². It is used for carpet, fabric, paving, and some landscaping measurements.
Derived by squaring the yard (3 feet). The yard was standardized to exactly 0.9144 m via the 1959 International Yard and Pound Agreement.
Square yards are used in carpeting (US and UK), fabric retail, paving (UK, US, India), and landscape gardening. In India, square yards are sometimes used in legal property documents.
Yard dates to medieval English usage; modern exact value standardized in 1959.
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.
