How to convert land units in India
Convert Bigha, Katha, Decimal, Acre and other Indian land units while checking the state, local factor and official land record.
First identify the place
Acre, square metre and square foot have standard sizes. Bigha, Katha and some other names can represent different areas in different states, districts or settlement systems.
Check the conversion factor
Choose the state and read the factor shown by the calculator. If your deed or local land office uses a different factor, use that verified local value instead of a general table.
Use one standard area as the bridge
A conversion can first turn the source unit into square feet, then divide by the target unit's square-foot factor. This makes the factor and calculation easy to inspect.
Verify legal measurements
An online conversion does not prove ownership, boundaries or official area. The registered deed, survey map and current government land record take precedence. Ask the relevant local authority or survey professional when the decision is legal or financial.
A transparent conversion example
For a documented local factor, first multiply the entered regional units by its square-foot equivalent. Then divide by the square-foot factor for the target unit. This exposes the only local assumption instead of hiding it.
When not to use a general converter
Do not rely on a general conversion for title, boundary, sale, inheritance, loan or dispute work. Use the record, survey and the relevant authorised process for that location.
Worked standard-unit bridge
Suppose a verified local record states that one unit equals 2,880 sq ft and the parcel contains 2.5 units. The first step is 2.5 × 2,880 = 7,200 sq ft. The same area is 7,200 ÷ 43,560 = about 0.1653 acre. The arithmetic is simple; the important evidence is the 2,880 sq ft local factor. Keep the place, status and source beside the result whenever it is copied.
Do not average conflicting factors
If two web pages give different figures for the same regional name, an average has no legal or measurement meaning. Check whether the sources describe different states, districts, settlement systems or historical contexts. Prefer a current official record or a source that clearly matches the parcel. If that evidence is unavailable, use a custom factor only after local verification or leave the conversion unresolved.
Record-check sequence
Start with the registered deed and note the exact unit spelling, district, village, survey or plot identifiers and recorded area. Compare that information with the current official state land-record service and survey map. Confirm whether mutation or later records changed the description. A calculator can translate a confirmed area into a standard unit, but it cannot establish ownership, encumbrance, boundary position or the validity of a document.
