Frequently Asked Questions (FAQs)

For official purposes and modern land records in Assam, 1 Bigha = 5 Katha is the standard conversion. However, some traditional areas, particularly in Central Assam, may use variations (4.5 Katha per Bigha). Always verify with local revenue records for 2026 transactions.

In Assam's standard measurement system, 1 Katha = 2,880 square feet. Therefore, 1 Bigha (5 Katha) equals 14,400 square feet. This conversion is essential for comparing traditional units with modern measurement systems.

Starting 2026, Assam's Revenue Department is implementing standardized digital land records where 1 Bigha = 5 Katha uniformly. While traditional variations exist, all new registrations and digital records will use this standardized ratio for consistency across the state.

For irregularly shaped land, first calculate the total area in square feet through professional survey. Then convert to Bigha (divide by 14,400), and finally to Katha (multiply by 5). For 2026 transactions, consider hiring a licensed surveyor for accurate measurements of irregular plots.

Yes, the 1 Bigha = 5 Katha conversion applies to both agricultural and non-agricultural land in Assam. However, agricultural land transactions may have additional documentation requirements. For 2026 agricultural planning, ensure your measurements align with local Circle Office records.

If your existing documents show a different ratio (like 1:4.5), maintain that ratio for consistency with historical records. However, for 2026 updates or new transactions, you should convert to the standard 1:5 ratio and document both values. Consult a local land records officer for transitional guidance.

Official verification can be obtained from:
  • Local Revenue (Circle) Office in your district
  • Assam's Dharitree online land records portal
  • District Commissioner's Office land records section
  • Registered land surveyors licensed in Assam
For 2026, prioritize digital verification through the Dharitree portal.

Key Takeaway for 2026

For 2026 property transactions, always verify measurements with updated digital land records through Assam's Dharitree portal and consult local authorities when traditional variations apply.
