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 (West Bengal)
A Bengal bigha is a traditional unit of land area used in West Bengal and Bangladesh, equal to approximately 1337.8 m² (about 0.33 acre).
Originated in pre-colonial Bengal land measurement. The Bengal bigha became standardized under British administration as 14,400 square feet, which equals 1337.8 m².
Bengal bighas are the standard unit in rural property transactions in West Bengal, Tripura, and Bangladesh. Land records use bigha alongside katha (1/20 bigha) and chatak (1/16 katha).
Standardized in colonial Bengal; widely used in modern West Bengal and Bangladesh.

Real-world example — Feature-scale to long-haul
One billion square inches equals exactly one bigha (west bengal) — the conversion an optical-network engineer performs when totalling feature-level path lengths into a single long-haul fiber-link distance.
1e+9 in² × 4.822544e-7 = 482.2544476005 bigha
Real-world example — Fiber-optic link lengths
Converting from microscale square inches to the bighas of a long-haul fiber link is the conversion an optical engineer performs when calculating attenuation per kilometre of fiber.
1e+9 in² × 4.822544e-7 = 482.2544476005 bigha
