Units that are not standard
Bigha varies more than any other unit — commonly 27,000 sq ft in western UP, about 17,400 sq ft in Bihar, 14,400 in West Bengal, and different again in Rajasthan, Gujarat, Assam and Haryana. Katha and Lecha vary similarly. Where a deal is quoted in these units, get the area restated in square feet or square metres in the agreement itself.
Quick reference
- 1 acre = 4,840 sq yd = 100 cents = 40 guntha = 4,047 sq m
- 1 hectare = 2.471 acres = 10,000 sq m
- 1 kanal = 20 marla = 5,445 sq ft
