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.
