Acre to Bihar Land Units
Convert acres to Katha, Dhur, Bigha and Decimal with a clearly stated local land convention.
How to use this tool
- Enter the acreage and keep Acre selected.
- Check the Katha size before using customary-unit results. Acre-to-square-feet conversion does not depend on Katha.
Worked example
One acre = 43,560 sq ft = 100 Decimal. At 1,361.25 sq ft/Katha, 1 acre = 32 Katha = 640 Dhur = 1.6 Bigha. Half an acre is 16 Katha at that same standard.
How it works
Enter the square feet in one Katha according to your local measurement convention. The initial 1,361.25 value is an illustrative convention, not an official statewide or district standard.
This tool assumes 20 Dhur = 1 Katha, 20 Dhurki = 1 Dhur and 20 Katha = 1 Bigha. Do not use it if those ratios differ in your local records.
One acre is 43,560 square feet; one Decimal/Dismil is 435.6 square feet. One square metre is approximately 10.7639104167 square feet. Conversion does not determine ownership, surveyed area or a legal boundary.
Local check: compare the unit and square-feet-per-Katha convention in the deed or revenue record before comparing two results. Displayed fractions are rounded; use a survey for boundaries or legal area.
FAQ
Does an acre change size when the local Katha size changes?
No. The acre remains 43,560 square feet. Only the number of local Katha, Dhur and Bigha needed to describe that area changes.
Is one Katha the same size everywhere in Bihar?
No. Local conventions can differ. Enter the value confirmed in your local records; do not infer it from a district name alone.
Why can another calculator show a different answer?
It may use a different square-feet-per-Katha value. Compare the measurement standard before comparing the results.
