Revenue records prevail. These are reference conversions. The area in your land record (khatauni, jamabandi, 7/12, patta, khatiyan, RTC) and the unit your tehsil or patwari uses are what count legally. Bigha, kattha and marla differ between states and even districts, so pick your local variant and confirm before you buy, sell or divide land.
