People use our numbers when they buy, sell or divide land, so we check them carefully.
Standard units
The acre, hectare, are, square meter, square foot and square yard have fixed definitions. Our converter uses the exact international definitions (1 foot = 0.3048 meter) and India’s legal metrology rules for metric units.
Local units
- Units such as bigha, biswa, katha, dhur and kuncham are not fixed by one national law. Their size comes from local practice, old settlement records and state rules.
- We use official government sources where they state a value, and widely used local values where they do not. Each state guide says which is which.
- Where sources disagree, we say so on the page instead of picking one value silently.
Calculations
Every figure on every page is calculated from one data file and checked by script. Our calculators use standard geometry formulas.
Corrections
Tell us about an error through the contact page. We fix confirmed errors quickly. Nothing on this site is legal advice; for a sale, partition or court matter, confirm the unit with your local revenue office.
