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 Dunam

A dunam (also dönüm or donum) is a unit of land area equal to exactly 1,000 m², used across Turkey, Israel, Palestine, Jordan, Lebanon, Iraq, and former Ottoman Empire territories. One dunam equals one stremma and one decare. The modern metric dunam of 1,000 m² was standardised during the British Mandate period; older Ottoman dunams varied by region (approximately 919-1,600 m²). It remains the primary land measurement unit for agricultural and property records throughout the Middle East, with properties routinely listed in dunams in Israeli and Palestinian real estate.
