Units explained
Square Inch
A square inch is an imperial unit of area equal to exactly 0.00064516 m², the area of a square with sides of one inch. It is widely used in the United States for small-area measurements.
Derived by squaring the inch. The inch was standardized to exactly 25.4 mm via the 1959 International Yard and Pound Agreement.
Square inches are used extensively in US engineering, manufacturing, real estate (for floor plans), and everyday small-area measurements. Engine displacement is often expressed in cubic inches but cross-sections in square inches.
Inch dates to medieval English usage; modern exact value standardized in 1959.
Bigha (Gujarat)
A Gujarat bigha is a traditional unit of land area used in Gujarat and parts of Rajasthan, equal to approximately 1618.74 m² (about 0.4 acre).
Originated as a traditional Gujarat land measure. The 1618.74 m² value corresponds to approximately 17,424 square feet.
Gujarat bighas appear in property records and agricultural transactions in Gujarat and bordering Rajasthan districts. Modern legal documents increasingly use hectares with bigha as the customary reference.
Traditional regional unit.
