Square Feet to Katha
Convert a square-foot area to कट्ठा using the local Katha size you specify.
How to use this tool
- Enter your area in square feet and keep Square feet selected.
- Enter the confirmed local Katha size before reading the Katha result.
Worked example
Katha = square feet ÷ square feet per Katha. For 2,722.5 sq ft at 1,361.25 sq ft/Katha: 2,722.5 ÷ 1,361.25 = 2 Katha. A 1,000 sq ft plot at the same standard is about 0.7346 Katha.
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
Why does the displayed result have fewer digits than my calculation?
Results are rounded for readability. The formula uses the entered values at higher precision. Do not use a rounded display as a survey measurement.
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.
