Why the size of a katha changes from place to place

Katha (also written kattha or cottah) was never a single national unit. It is a fraction of a bigha, and the bigha itself was fixed differently by each old survey. The 720 sq ft katha comes from the standard bigha of 14,400 sq ft used in Bangladesh and West Bengal. Elsewhere the same word means a different area:

• Bihar (Patna): 1 katha = 1,361 sq ft. Use the Bihar katha converter.
• Assam: 1 katha = 2,880 sq ft (5 katha = 1 bigha).
• Nepal: 1 katha = 3,645 sq ft (20 katha = 1 bigha of 72,900 sq ft).

For a sale deed or a mutation (namjari) always use the size written in the mouza map or the deed, not a rule of thumb.
