One acre is equivalent to 1.6 bighas. However it's essential to note that the size of a bigha varies by region in India. In Punjab and Haryana one bigha is approximately 0.625 acres; in Rajasthan it's about 0.625 acres. Conversely in West Bengal one bigha is closer to 0.33 acres. This variation is due to historical and regional differences in land measurement practices. Therefore when converting acres to bighas it's crucial to consider the specific regional context to ensure accuracy. Using 1.6 bighas per acre is a common approximation for most general purposes.
