Assam land units, explained
Land in Assam is measured in Bigha (বিঘা), Kotha (কঠা) and Lesa (লেচা). The hierarchy is simple: 1 Bigha = 5 Kotha, and 1 Kotha = 20 Lesa — so a Bigha is 100 Lesa, or exactly 14,400 square feet.
Spellings vary — Kotha is often written Katha, and Lesa appears as Lecha — but they are the same units. What genuinely changes is the size across state lines: in Bihar and parts of Uttar Pradesh a bigha is much larger, and West Bengal divides its bigha into 20 katha where Assam uses 5 kotha. Everything on this page uses the Assam standard.
The converter above handles a single unit or a full plot size like 3 Bigha 2 Kotha 8 Lesa, in either direction — into square feet, square metres, acres and hectares, or back.
