Why does Kattha size vary between Banka and Deoghar? Here is how regional Amin tradition works:
A Laggi (pole/bamboo standard) is the fundamental linear measuring rod used by revenue Amins. 1 Haath is standardized as 18 inches (1.5 feet). A 6-haath Laggi is 9 feet long; 1 square Laggi equals 1 Dhur (81 sq.ft), and 20 Dhurs equal 1 Kattha (1,361.25 sq.ft).
1 Acre always equals 100 Dismils (43,560 sq.ft), which means 1 Dismil is strictly 435.6 Sq.Ft. However, because Kattha depends on the local Laggi, 1 Kattha can equal approximately 3.125 Dismils (in 6-haath regions) or ~3.67 Dismils (in 6.5-haath regions).
Sale deeds (केवाला) often mention Kattha or Decimal based on ancestral records. When surveyed with Gunia and ETS on the actual plot, encroachments and Seemana pillar triangulations frequently reveal area discrepancies.
