About Bighas
A bigha is a traditional South Asian land area unit used across India, Nepal, and Bangladesh, with its size varying significantly by region. The standardised pucca bigha (common in Uttar Pradesh and Bihar) equals 3,025 square yards (approximately 2,529 m²). In West Bengal it is approximately 1,337 m², in Rajasthan around 1,618 m², and in Nepal over 6,773 m². Despite metrification, bigha remains the dominant land measurement in rural India. When dealing with legal or property matters, always verify the local definition, as regional variants differ substantially.
About Square Chains
A square chain (ch²) is a surveying unit equal to the area of a square with sides of one Gunter's chain (66 feet or ~20.12 m), approximately 404.69 m². Ten square chains equal exactly one acre, making it the natural subdivision unit in traditional land surveying. The US Public Land Survey System used chains to lay out townships and sections, and square chains appear throughout old legal property descriptions and government land grants across North America. One square chain equals exactly 16 square rods.
