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 Link
A square link is an imperial unit of area equal to approximately 0.0405 m². It is part of the chain-link surveying system used historically for land measurement.
Derived by squaring the link (1/100 of a chain = 7.92 inches). The Gunter's chain was introduced by English mathematician Edmund Gunter in 1620 for land surveying.
Square links appear in historical land surveys and legacy property records, particularly in the US Public Land Survey System (PLSS). Modern surveys use feet or meters instead.
Gunter's chain introduced in 1620; standardized via the 1959 International Yard and Pound Agreement.
