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.
Manzana
A manzana is a unit of land area used in several Central American countries, equal to approximately 6988.96 m² (about 0.7 hectare or 1.73 acres).
Originated as a Spanish colonial unit. Standardized at exactly 10,000 square varas (Spanish varas of about 0.836 m each).
Manzanas are still widely used in agricultural records and rural property in Nicaragua, Honduras, Costa Rica, Guatemala, and some other Central American countries. Used alongside hectares in modern legal documents.
Spanish colonial origin; remains in popular Central American use.
