Frequently Asked Questions
Unlike Acre or Hectare, Bigha is a traditional, non-SI unit whose size was set historically by local revenue systems, so it differs widely from state to state - for example, a Punjab Bigha is much smaller than a Uttar Pradesh "pucca" Bigha.
In states like Uttar Pradesh and Rajasthan, a "pucca" (standard) Bigha is larger, while a "kaccha" Bigha is a smaller, informal local variant - often a simple fraction of the pucca Bigha. This calculator uses the standard pucca Bigha value.
Bigha size can even vary between districts within the same state. Select "Other / Custom" and enter the exact square feet used in your local land records for the most accurate conversion.
