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 Megameters
A square megameter (Mm²) equals the area of a square with sides of one million meters - 10¹² m², or one trillion square meters. At this scale we describe major geographic and planetary regions. The entire land surface of Earth is about 149 Mm², the Indian Ocean covers roughly 70 Mm², and the Sahara Desert spans approximately 9.2 Mm². Square megameters provide a convenient scale for comparing continent-sized areas without resorting to hundreds of millions of square kilometers.
