Assam Land Measurement Units
Assam does not share one national "standard Bigha." Revenue offices, farmers, and city brokers may use different unit sizes — and the wrong assumption can change an quoted plot area by 25% to 400%. This hub lists every variable unit BhumiMeter tracks for Assam, with square-foot, acre, and square-metre equivalents computed from our verified data file (not AI estimates). Use the pre-set converter below, then cross-check on your state land-records portal before paying earnest money.

What brokers & patwaris actually use
Assam Bigha (14,400 sq ft) and Katha (2,880 sq ft) differ sharply from Bengal — a common mistake for buyers crossing the border from Siliguri. Lecha (144 sq ft) appears in older Assamese deed templates.
Common pitfalls in Assam
- Verifying only the broker's conversion, not the government Khasra/Khatian area.
- Signing on square feet when the registered deed lists Bigha or Katha.
- Using another state's Bigha standard from memory or a generic Google result.
