Convert land plot size between sq ft, sq metres, acres, and bighas. Free tool for real estate measurement standardization.
Plot Size Converter: Calculate Land Area in All Units
Land measurement inconsistency creates confusion in Indian real estate. According to a 2024 NAREDCO (National Real Estate Development Council) survey, 58% of property disputes involve plot size misrepresentation or unit conversion errors. The same plot marketed in multiple units (₹18 lakhs per sq ft OR ₹1,936 per sq metre OR ₹45 lakhs per sq yard) creates confusion unless conversions are precisely performed.
Our free plot size converter standardizes land measurements across all Indian and international units—sq ft, sq metres, acres, bighas, annas, and hectares—enabling accurate property comparison and negotiation. This comprehensive guide explains historical measurement systems, explores regional variations, and provides strategies for verifying plot sizes during property transactions.
Land Measurement Units: Complete Reference
Understanding Unit Systems in India
Land measurement in India follows three overlapping systems:
System 1: Imperial Units (British Colonial Legacy)
- Sq Feet (sq ft)
- Yards (yd²) = 9 sq feet
- Acres = 43,560 sq feet
- Still widely used in urban properties
System 2: Metric Units (International Standard)
- Sq Metres (sq m)
- Hectares = 10,000 sq metres
- Official legal measurement in India since 1957
System 3: Traditional Indian Units (Regional Variation)
- Bigha (varies by state: W. Bengal 1,250 sq m, Bihar 1,000 sq m, Delhi 2,500 sq m)
- Anna = 1/16 of a bigha
- Cents (South India) = 100 sq metres
- Guntha (Maharashtra) = 100 sq metres
- Kanal (Punjab) = 250 sq metres
- Marla (Punjab) = 30.25 sq metres
Practical consequence: Same "1 bigha" plot in West Bengal (1,250 sq m) vs Delhi (2,500 sq m) represents 100% size difference yet identical terminology.
Unit Conversion Fundamentals
Core Conversion Factors
| From | To | Multiply By | Example |
|---|---|---|---|
| Sq Feet | Sq Metres | 0.0929 | 500 sq ft = 46.45 sq m |

| Acres | Sq Metres | 4,047 | 1 acre = 4,047 sq m |
| Sq Metres | Acres | 0.000247 | 10,000 sq m = 2.47 acres |
| Hectare | Sq Metres | 10,000 | 1 hectare = 10,000 sq m |
| Hectare | Acres | 2.471 | 1 hectare = 2.471 acres |
| Bigha (Delhi) | Sq Metres | 2,500 | 1 bigha = 2,500 sq m |
| Bigha (Bengal) | Sq Metres | 1,250 | 1 bigha = 1,250 sq m |

| Cent | Sq Metres | 100 | 1 cent = 100 sq m |
Urban vs Rural Variations
Urban properties (cities):
- Measured in: Sq feet or sq metres
- Documented as: Sq feet (older registrations) or sq metres (post-2000)
- Example: Mumbai apartment "1,100 sq ft" = 102.2 sq metres
Rural/Agricultural land (villages):
- Measured in: Traditional units (bighas, annas, gunthas)
- Conversion to metric essential for legal documentation
- Example: Delhi village "2 bighas" = 2 × 2,500 sq m = 5,000 sq m = 1.23 acres
Transitional areas (semi-urban):
- Often mix both systems
- Deeds may show "2 bighas 4 annas = 406.25 sq metres"
- Conversion errors common between traditional and metric
Regional Unit Variations: State-by-State Guide
Northern India
Delhi & Haryana:
- Bigha = 2,500 sq m (largest bigha in India)
- Anna = 156.25 sq m
- Property registered in Delhi might use either "2.5 bigha" (exact metric decimal) or "2 bigha 8 anna" (traditional fraction)
- Example: Property advertised as "₹1 crore for 1 bigha Delhi" = ₹40,000 per sq m
Punjab:
- Kanal = 250 sq m (official unit)
- Marla = 30.25 sq m
- Typical urban plot = 5 marla = 151.25 sq m
- Registration often shows "5 marla = 151.25 sq m" (metric conversion)
Himachal Pradesh:
- Biswa = 50 sq m (very small unit)
- Marla = 30.25 sq m
- Mostly uses metric officially; older deeds use traditional units
Western India
Maharashtra:
- Guntha = 100 sq m (standard)
- Anna = 12.5 sq m (very small)
- Property: "4 guntha" = 400 sq m (common residential plot)
- Conversion: "₹50 lakhs for 4 guntha" = ₹1,250 per sq m
Gujarat:
- Bigha (variable, often 1,600-1,800 sq m)
- Default: Use metric (sq m) in formal documents
- Registration: "2 bigha = 3,200 sq m" (per local definition)
Southern India
Tamil Nadu, Karnataka, Telangana, Andhra Pradesh:
- Cent = 100 sq m (universal southern unit)
- Property: "5 cent" = 500 sq m = standard residential
- Conversion: "₹40 lakhs for 5 cent" = ₹80,000 per sq m
Kerala:
- Cent = 100 sq m
- Or direct metric (sq m)
- No ambiguity; consistent system
Eastern India
West Bengal, Odisha, Bihar:
- Bigha = 1,250 sq m (Bengal bigha)
- Anna = 78.125 sq m
- Property: "2 bigha" = 2,500 sq m (common agricultural)
- Alert: Same "2 bigha" term represents 5,000 sq m in Delhi but 2,500 sq m in Bengal—100% variation!
Critical for transactions:
- Always confirm the state/region's bigha definition
- Spec sheet must show both traditional unit AND sq metre equivalent
- Pre-transaction: Request metric conversion certificate from local revenue office
Plot Size Comparison Framework
How to Use Conversions in Property Shopping
Scenario 1: Comparing properties across cities
Property A (Delhi): Listed as "1 bigha"
- Delhi bigha = 2,500 sq m
- Price: ₹1 crore
- Cost per sq m: ₹40,000
Property B (Bangalore): Listed as "0.6 acres"
- 0.6 acres = 2,430 sq m (similar size)
- Price: ₹1.2 crore
- Cost per sq m: ₹49,383
Conclusion: Delhi property 23% cheaper per sq m despite same size.
Scenario 2: Identifying misrepresentation
Agent claims: "1-acre premium plot" Actually shown: 3,000 sq m plot Real conversion: 3,000 sq m = 0.74 acres Red flag: 26% smaller than advertised
Scenario 3: Hidden price tricks
Price advertised: "₹18 lakhs per sq ft" Equivalent: ₹18 × 10.764 = ₹193,600 per sq metre (extremely high) Or conversion: ₹18 per sq ft × 43,560 sq ft/acre = ₹783,600 per acre (reality check: ₹7.8 crores per 2 acres, reasonable for premium location)
Different unit conversions create 10-100x variation perception.

Real Estate Transactions: Unit Conversion Best Practices
Pre-Purchase Verification
Step 1: Obtain Official Dimensions
- Request registered deed (old registration document)
- Request mutation certificate (latest updated record)
- Request measurement survey by licensed surveyor (₹2,000-₹5,000)
- Goal: Get measurement in both traditional unit AND square metres
Step 2: Convert to Standard Units
- Use our calculator to convert deed measurements to metric
- Compare against advertisement claim
- If advertisement shows "1 bigha", verify:
- State definition of bigha
- Official 2,500 sq m equivalent (Delhi) or regional variant
- Actual survey shows same or greater
Step 3: Verify Price per Unit Consistency
- Calculate "price per sq m"
- Compare against neighbourhood average
- Wildly different price per sq m may indicate measurement mismatch
Example transaction verification:
Property shown: "₹80 lakh for 1 acre, Haryana"
- Standard conversion: 1 acre = 4,047 sq m
- Implied price: ₹80,00,000 ÷ 4,047 sq m = ₹19,768 per sq m
- Region benchmark: Haryana standard ₹15,000-₹25,000 per sq m (reasonable)
Property shown: "₹50 lakh for 1 bigha, Bengal"
- If using Bengal bigha: 1 bigha = 1,250 sq m
- Implied price: ₹50,00,000 ÷ 1,250 sq m = ₹40,000 per sq m
- Region benchmark: Bengal standard ₹8,000-₹15,000 per sq m (RED FLAG: 3x overpriced)
- Action: Demand surveyor verification or renegotiate
Common Conversion Errors in Real Estate
Error 1: Confusing Bigha Definitions
Typical mistake: Seller quotes "1 bigha" (assuming Delhi definition 2,500 sq m), buyer assumes Bengal definition (1,250 sq m).
Result: Buyer pays ₹50 lakh expecting 1,250 sq m but receives 2,500 sq m property (good error for buyer) OR vice versa (catastrophic for buyer).
Prevention:
- Convert both definitions using calculator
- Specify in purchase agreement: "1 bigha shall mean 2,500 sq metresper Delhi revenue department"
- Attach official conversion certificate to deed
Error 2: Unit Ambiguity in Price Quotes
Quote 1: "₹18 lakhs per sq ft" (extremely high)
- Conversion: ₹18 × 10.764 = ₹193,600 per sq m (luxury segment)
Quote 2: "₹10,000 per sq m" (very low)
- Conversion: ₹10,000 ÷ 10.764 = ₹929 per sq ft (below market)
Prevention: Always clarify unit in written quote. "₹50 lakhs for exact plot of 25 sq metres shall mean ₹20,000 per sq metre" removes ambiguity.
Error 3: Rounding Errors in Deed
Example: Deed states "approximately 2.5 acres"
- Actual survey: 2.4 acres (3.8% smaller)
- Using "2.5 acres" for calculation: ₹5 crore ÷ 2.5 = ₹2 crore per acre
- Using actual "2.4 acres": ₹5 crore ÷ 2.4 = ₹2.08 crore per acre
- Difference: ₹4 lakhs variance on total price
Prevention:
- Deed must specify "exactly 2.4 acres, as per survey deed number XXX"
- Survey report becomes part of legal transaction
- Remove word "approximately" from measurement clauses
Error 4: Legal Unit Vs Advertised Unit Mismatch
Registration record: "2,500 sq m" (legal) Advertisement: "1 bigha" (marketing) But: If region's bigha differs from 2,500 sq m, discrepancy exists
Example:
- Property registered in Haryana as "2,500 sq m"
- Marketed as "1 bigha" (technically correct for Delhi, not Haryana)
- Haryana standard bigha ≠ 2,500 sq m = legal ambiguity
Prevention: Documentation must state exact conversion. "2,500 sq m, equivalent to 1 bigha as per Delhi revenue definition; applicable in Haryana context as modified standardization."
Plot Size in Budget Calculation
How Plot Size Affects Property Value
Value factors by plot size:
| Plot Size | Classification | Typical Cost (₹/sq m) | Annual Appreciation |
|---|---|---|---|
| 100 sq m | Micro | ₹50,000-₹80,000 | 5-7% (compact plots) |
| 250 sq m | Small | ₹40,000-₹60,000 | 6-8% (popular size) |
| 500 sq m | Medium | ₹35,000-₹50,000 | 6-9% (villa potential) |
| 1,000 sq m | Large | ₹30,000-₹45,000 | 7-10% (farm/villa plots) |
| 2,500 sq m+ | Very Large | ₹15,000-₹35,000 | 8-12% (agricultural/investment) |
Note: Price per sq m typically decreases as total plot size increases (large plots discount). However, total property value increases (1,000 sq m at ₹30K/sq m = ₹3 crore total, more valuable than 250 sq m at ₹40K/sq m = ₹1 crore total).
Plot Size Optimization for Different Buyers
First-time home buyer (₹20-40 lakh budget):
- Target size: 200-400 sq m (typical 2-3 BHK footprint)
- Conversion check: 300 sq m = 3,230 sq ft (good for project layouts)
- Per sq m price: ₹50,000-₹67,000
Investment buyer (₹1-2 crore budget):
- Target size: 1,000-2,500 sq m (land banking potential)
- Conversion check: 2 acres ≈ 8,094 sq m (large villa plot)
- Per sq m price: ₹15,000-₹25,000 (negotiable with larger lots)
Commercial developer (₹5-10 crore budget):
- Target size: 10,000+ sq m (multi-unit project viability)
- Conversion check: 2.5 acres ≈ 10,117 sq m (minimum for apartment complex)
- Per sq m price: ₹5,000-₹15,000 (wholesale land rates)

Conclusion: Standardize Land Measurements
Land measurement inconsistency remains a source of real estate disputes in India. Our free plot size converter streamlines unit conversions across 11 different measurement systems, enabling accurate property comparison, transaction verification, and budget calculation.
Key takeaways:
-
Regional units critical: Same "1 bigha" means 2,500 sq m in Delhi but 1,250 sq m in Bengal—state definition governs
-
Formal conversion essential: All purchase agreements must specify metric equivalents (sq metres), not just traditional units
-
Price per sq m reveals truth: Calculate price per sq metre for any property; wildly different rates indicate measurement discrepancy
-
Documentation verification: Obtain survey report, mutation certificate, and licensed measurement before committing funds
-
Unit selection affects valuation: "₹18 per sq ft" vs "₹194 per sq m" (same price, different perception)
The typical property transaction benefits from verification using our plot size converter to align advertised measurements, legal documentation, and agreed pricing per unit. Conversion precision prevents costly disputes later.
