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 (Pucca, North India)
A pucca (full) bigha is a traditional unit of land area used in North India, equal to approximately 3025 m² (about 0.75 acre). Used in Uttar Pradesh, Bihar, Uttarakhand, and parts of Madhya Pradesh.
Originated as a traditional Indian agricultural land measure. The 'pucca' (literally 'cooked' or 'full') bigha distinguishes it from the 'kachha' (raw or half) bigha, which is one-third as large.
Pucca bighas appear in land records, property deeds, and agricultural statistics across North India. The exact size can vary between districts; 3025 m² is the most common standardized value in Uttar Pradesh.
Traditional unit; standardized in different ways by different state governments over time.
