Unit of measurements:
In North India generally there are three types of unit of measurement of land. These are
1. Kanal marla system 2. Bigha Biswa system 3. Meter system
The third one is most common now and in new measurements and documentation it is used, the conversion of above two with 3rd one is as under:
Kanal marla System
1 Hectare = 10000 m2 = 2.5 Acres
1 Acre = 4000 m2 = 8 Kanal
1 Kanal = 500 m2 = 20 Marlas
1 Marla = 25 m2
Bigha Biswa system
1 Hectare = 10000 m2 = 2.5 Acres
1 Acre = 4000 m2 = 1.59 ~1.60 Bigha (Pukhta / Bada bigha)
1 Acre = 4000 m2 = 4.72 Bigha (Kachha/Chota bigha)
1 Bigha = 2529 m2 (pukhta) or 847 m2 (Chota)
In some areas one bigha is also considered for 800 m2 only.
In revenue documents there are mainly three types of records i.e. Jamabandi, Girdwari, Map (sajra or latha). In some area fard haquit is also issued. This is the consolidated document of total land holding of individual and present market rate is mentioned. Jamabandi reflect the total land ownership, its type, source of irrigation etc., however girdwari represent the cultivation pattern, crop growing of land etc, therefore girdwari is made in every crop season i.e. after 6 months however jamabandi is made after 4-5 years. Map represents the actual position of land with important land marks.
