About the Area Converter

Area measurement in India is uniquely complex because it involves at least three overlapping systems: the metric system (square meters, hectares), the imperial system (square feet, acres, square yards), and an array of traditional regional units. Square feet dominate residential real estate in most cities; acres and hectares are used in agriculture; and units like bigha, gaj, gunta, cent, and ground are used in specific states and property segments. A buyer from Maharashtra looking at agricultural land in Tamil Nadu may be quoted in cents - an unfamiliar unit that requires conversion to make sense of the price.

The complexity increases because even the regional units are not standardized nationally. Bigha in Uttar Pradesh (2,529 sq m) is nearly twice the bigha in Madhya Pradesh or West Bengal (1,337 sq m). Gaj can mean a square yard (83.6 cm sides) in some contexts and a linear yard in others. When a property listing uses these terms, the buyer must know both the unit name and the state-specific definition to avoid calculating at the wrong scale. This converter uses the most common standardized values for each regional unit.

For agricultural and government contexts, hectares are the global standard. The land records systems in India are progressively converting to metric units, but older records and rural transactions still use traditional units. Satellite surveys use square meters and hectares; FSI (Floor Space Index) calculations for urban development are in square meters; but ground-level negotiations often happen in traditional units. Being fluent across all three systems prevents the significant misunderstandings that arise when a buyer and seller are nominally speaking the same language but using different unit assumptions.

Tips & Insights

• 1

  RERA mandates that developers disclose apartment sizes in carpet area (usable floor space). Carpet area is typically 70-75% of super built-up area used in older marketing. Always ask for and compare on carpet area to make accurate price-per-sq-ft comparisons across projects.

  1 acre = 43,560 sq ft = 4,047 sq m = 40.47 cents = 0.405 hectares. This conversion cluster covers most agricultural land transactions in India. Keep it handy when evaluating rural property listings.

• 3

  The bigha varies significantly by state: UP bigha = 2,529 sq m (roughly 0.625 acres); West Bengal and MP bigha = 1,337 sq m (0.33 acres). Always confirm which state definition is being used before calculating land area or comparing price per bigha across regions.

• 4

  Tamil Nadu property in Chennai and nearby districts is frequently quoted in grounds (1 ground = 2,400 sq ft = 222.97 sq m). A plot of 3 grounds = 7,200 sq ft = 669 sq m - comparable to a mid-size residential plot. This unit does not appear in most standard converters.

• 5

  In South India (Karnataka, Andhra Pradesh, Telangana), land area is quoted in guntas. 1 gunta = approximately 101 sq m = 1,089 sq ft. 40 guntas = 1 acre. This 40-guntas-per-acre relationship is the key ratio to remember for that region.

• 6

  For international property comparison, use hectares. 1 hectare = 10,000 sq m = 2.47 acres = 107,639 sq ft. European farmland and international commercial properties are quoted in hectares - converting to a common unit makes cross-border land price comparisons possible.

• 7

  FSI and FAR calculations required for urban development approval use square meters exclusively. A plot of 500 sq m with FSI 2.0 allows 1,000 sq m of built-up area. Converting the plot size accurately from sq ft or sq yd to sq m before applying FSI prevents costly errors in building permit applications.
