Traditional Indian land units vary by state, which is why conveyancing always states the local definition. The Uttar Pradesh bigha is about 2529 square metres, so five bigha is 1.26 hectares or 3.12 acres. Bihar uses katha subdivisions at 126.44 square metres, and southern states use cents at 40.47 square metres.
