How to use the area converter
Four steps, about five seconds. Nothing is stored and nothing is sent anywhere — the whole calculation runs on your device.
Type the area
Enter the number exactly as it appears in the listing or the deed. Decimals are fine — 2.5 acre works as well as 2500.
Pick the source unit
Choose what that number is currently measured in: square feet, gaj, bigha, kanal, cent, or any of the 26 units in the list.
Choose the target
Select the unit you actually think in. The result updates as you type, and the swap button flips both sides in one click.
Read every unit at once
The panel on the right lists the same area in all 26 units, so you can copy whichever one the buyer, bank or registrar asks for.
Area unit reference table
One unit of each measure expressed in square feet, square metre and square yard (gaj).
| Unit | Square Feet | Square Metre | Square Yard (Gaj) | Acre |
|---|
Bigha, Kanal & Marla vary by state
Unlike sq ft or sq m, traditional Indian units have no single national definition. Always confirm the local value before signing a land deal.

Why an area converter matters
Compare listings fairly
A flat quoted in sq ft and a plot quoted in gaj can't be compared side by side. Convert both to one unit first, then compare the per-unit price.
Read documents correctly
Sale deeds, khasra records and mutation papers often use bigha, biswa or kanal. Converting them tells you exactly how much land you are buying.
Price the land right
Circle rates are published per sq m or per acre depending on the state. Convert your plot size to that unit to estimate stamp duty and registration cost.
Understanding the common area units
Square Feet (sq ft) is the default unit for apartments, builder floors and built-up area across India. One square foot is a square measuring one foot on each side, or roughly 0.0929 square metres.
Square Metre (sq m) is the SI unit and the one used on approved building plans, RERA filings and most government circle-rate tables. One square metre equals about 10.764 square feet.
Square Yard or Gaj dominates plot sales in Delhi NCR, Haryana, Punjab and Rajasthan. One gaj is 9 square feet, so a 200-gaj plot is 1,800 sq ft.
Acre and Hectare are the units of agricultural and large commercial land. One acre is 43,560 sq ft; one hectare is 10,000 sq m, or roughly 2.471 acres.
Bigha, Biswa, Kanal, Marla, Guntha, Cent and Ground are regional units still used in revenue records. Their size changes from state to state — see the table above before you rely on a number.
The maths behind the conversion
Every unit on this page is defined against one exact constant, so no two tables can drift apart.
Frequently asked questions
An area converter is a tool that rewrites a land or floor measurement from one unit into another — for example square feet into square metres, or gaj into bigha — so that two differently quoted properties can be compared on the same scale.
One square metre equals 10.7639 square feet. To go the other way, multiply square feet by 0.0929 to get square metres.
1 gaj (square yard) is exactly 9 square feet. So a 100-gaj plot is 900 sq ft and a 250-gaj plot is 2,250 sq ft.
1 acre is 43,560 square feet, 4,840 square yards or 4,046.86 square metres. One hectare contains about 2.471 acres.
Bigha is a traditional unit with no national standard. It ranges from roughly 12,000 sq ft in Madhya Pradesh to 27,225 sq ft for a pucca bigha in Uttar Pradesh and Rajasthan. This area converter uses the pucca bigha and publishes a state-wise table alongside it.
Both are used in Punjab, Haryana, Himachal Pradesh and Jammu & Kashmir. 1 kanal equals 20 marla, which works out to 5,445 sq ft or 605 sq yards. One marla is therefore 272.25 sq ft.
No. Carpet area is the usable floor area inside the walls. Built-up area adds the walls and balcony, and super built-up area also adds a share of common spaces. This tool converts units, not area types — ask the seller which area type the number refers to.
Yes. The Lets Rentz area converter is completely free, needs no sign-up, and runs entirely in your browser — nothing you type is sent to a server.
Use them for comparison and planning. For registration, stamp duty or any legal filing, go by the measurement recorded in the local revenue or municipal document.
