Land records (khatian) state area in acres and decimals. Deeds and local usage often state bigha, katha and chhatak.
Local measures differ
The size of a bigha or katha is not the same everywhere. Some areas use a different local bigha, and other States use very different values. When money depends on the figure, rely on the area in acres or decimals in the record, or on a survey.
