Why This Conversion Comes Up in Real Land Deals
This is the experience for most buyers. You have come across the property listed as ‘2.5 hectares available for agricultural conversion.’ Broker tells you that the same plot of land is ‘a little over 6 acres.’ The bank manager wants the dimensions in sq ft for the valuation report. The measurements given in the pahani of the revenue department are in hectares and guntas.
Four different measurements. Same plot.
And there’s no surprise in it. India is a country that uses as many as five different measurements simultaneously. A hectare is the government’s measurement; brokers refer to plots in acres. Cents and guntas in South India, bigha and biswa in North India, and for the RERA project report, square feet is used. Converting hectares to acres is not mathematics; it helps you confirm that every document in your property folder belongs to the same land.
The Formula
Hectares to Acres:
Acres = Hectares × 2.471
Acres to Hectares:
Hectares = Acres × 0.4047

What Is a Hectare — And Where Will You See It?
A hectare is a SI unit of area equal to 10,000 sq metres (or a 100m x 100m square). It’s in the SI unit system and used in every revenue/government official document across the world.
In India, the hectare is used in the following places:
Revenue & Govt Documents: Pahani (Record of rights) in Karnataka, mutation certificate, mutation land records for district land records of Karnataka, AP, Maharashtra, and TN mention the land area in hectares. RTC (Record of Tenancy & Cultivation) records the area in hectares. If you buy agricultural land, or if you have an application for conversion pending.
RERA registration of the project: For township or large plotted development projects that apply for RERA registration, the entire land area will be cited in hectares. For example, AR Belle Vie of SSP Group sprawls over 25 acres (10.12 hectares approx.) and will be stated in the RERA filing.
Sale & purchase of agricultural land: Farmlands and plantation lands in South India are measured in hectares when dealings are involved with the Govt although they are often converted to acres for a buyer by a local realtor.
Geographical docs & zone data: Master plan zone maps, town planning schematics & forest border maps use hectares as the measuring unit.
What Is an Acre — And Where Will You See It?
An acre is a unit to measure a land area, developed during the medieval days in England, where an acre represented the amount of land that a man could plough in a single day with an oxen, is now standardised as 4,047 sq mtrs, equivalent to 43,560 sq ft. Popular usage of acre in India: Advertisements-Sale of plotted development projects, farmhouse plots or plots within gated communities are sold using ‘acres’ as a unit. ‘10 acre gated township’ would be much better understood by buyers than a ‘4.05-hectare township’. Sale and Purchase of agricultural land: The purchase and sale of agricultural lands in the southern states of India, Karnataka, Tamil Nadu, Kerala and Andhra Pradesh are carried out in acres. Land below one acre is traded in guntas (40 guntas equal to one acre). Evaluation of agricultural land: Agricultural land or semi-urban property is valued and quoted by banks at so many rupees per acre for lending purposes. Sale of massive real estate projects: While a developer launches a huge township project in India, the first news the market takes is the dimension of the land where the township is being built – i.e ‘25 acre township’.
How to Visualise These Units — A Real Reference
Abstract numbers are difficult to think about when you are standing on a piece of land. The analogies make the measurement tangible:
1 Hectare is approximately:
- 1.4 times the size of an international standard football field
- 100 x 100 metre square plot of land (approximately 328 ft x 328 ft)
- Large enough for about 11 standard 40×60 ft Bangalore residential sites
- 1,07,639 sq ft – or approximately 11-15 crore in Bangalore market price at present rates at the periphery (10,000-14,000/sq ft).
1 Acre is approximately:
- The size of a football field, including runoff.
- 209 x 209 ft plot of land (approximately)
- 4-5 standard 40×60 ft Bangalore residential sites
- 43,560 sq ft – approximately 4.35 crore per acre at the price of 10,000/sq ft at peripheral price.
Three Real Estate Scenarios Where This Conversion Matters
Scenario 1 — Verifying Land Documents Before Purchase
You are purchasing a 4-acre agricultural piece of land close to Bangalore which is now converted to a residential property. The Sale Deed mentions 1.6187 Hectares. Before signing the Sale Deed, you convert: 1.6187 2.471 = 4.0 acres. It matches-you are not cheated.
Had it said 1.5 Hectares (3.7 acres) the difference of 0.3 acres at 40 lakh an acre is a difference of 12 lakh cleverly disguised in a units difference. This is the way fraud-or error at least-occurs if buyers do not cross check by converting units.
Scenario 2 — Comparing a Government Land Record with a Listing
This shows 0.82 hectares on the RTC. On a real estate portal it says 2 acres. Convert 0.82 to 0.82 * 2.471 = 2.026 acres. This is sufficiently close – the difference of 0.026 acres is acceptable as rounding error. The document is talking about the same plot.
If 0.70 hectares on the RTC (1.73 acres) was on the listing and said 2 acres. Red flag – explain the discrepancy before moving on.
Scenario 3 — Evaluating a Township Project’s Land Bank
A developer promises a ’20 hectare integrated township’. You want to know how it compares with their rival’s ’55-acre project’ within the same corridor?
20 hectares = 20 x 2.471 = 49.42 acres
Rival’s project: 55 acres
This implies the rival’s project is approximately 11% bigger. When dealing with land-intensive projects such as plotted development or villa townships, the size of the total land bank matters to the extent of deciding plot density, green spaces, etc., thus eventually deciding the quality of living.
AR Belle Vie by SSP Group comprises of 25 acres (10.12 hectares) at the STRR corridor, East Bangalore and includes 221 villas & 464 apartments in a single gated township with 40+ amenities and a huge dedicated 38,000+ sq ft clubhouse. RERA approved. Explore the project →

Where Each Unit Is Commonly Used in India
| State / Region | Dominant Unit in Real Estate | Government Records Use |
| Karnataka | Acres, Guntas, Square Feet | Hectares (RTC / Pahani) |
| Tamil Nadu | Acres, Cents, Square Feet | Hectares |
| Kerala | Cents, Acres | Hectares |
| Andhra Pradesh / Telangana | Acres, Guntas | Hectares |
| Maharashtra | Acres, Square Feet | Hectares |
| Punjab / Haryana | Acres, Marla, Kanal | Hectares |
| Uttar Pradesh / Rajasthan | Bigha, Biswa, Acres | Hectares |
| Delhi NCR | Square Yards, Square Feet | Hectares |
The practical takeaway: whichever unit a listing uses, always convert to square feet for an apples-to-apples price comparison across different geographies, and always verify the area against the government land record (which will be in hectares) before finalising any purchase.
Key Takeaways
- 1 Hectare = 2.471 acres
- 1 Acre = 0.4047 Hectares
The Government records (RTC, pahani, mutation) will record land area in hectares. But while buying and selling of land or real estate, the acreage measure is commonly used. So always verify the area of land against the revenue record before closing any transaction, converting into a similar measure to verify consistency.
If it is a RERA-approved residential layout plot/flat, it would be recorded in square feet. Again, please do check for conversions.
