Gaj to square yard converter: the Indian land unit explained
A gaj is exactly equal to a square yard — 1 gaj = 1 sq yd = 9 sq ft = 0.8361 square metres. It is the traditional land-area unit of northern India, still in everyday use in Delhi NCR, Punjab, Haryana, Uttar Pradesh, and parts of Rajasthan. Property listings in those markets quote prices per gaj alongside (or instead of) per square foot. The conversion is mathematically simple but commercially important when comparing plots across regions and unit systems.
The word gaj comes from Hindi/Urdu and originally meant “yard” (the length unit). Today, when used in real-estate context, it refers to the square yard — the area of a 3-foot × 3-foot square, equal to 9 square feet. The two meanings (length and area) coexist; context determines which is meant.
What is a gaj?
In modern Indian property transactions, a gaj is a unit of area equal to one square yard. The international yard is defined as 0.9144 metres (1959 agreement), so a gaj equals (0.9144)² = 0.83612736 square metres exactly. That is the master conversion factor.
Physically, a 1 gaj plot would be a 3-foot × 3-foot square — roughly the footprint of a dining-room chair. A 100 gaj plot is 900 sq ft = 83.6 m², comparable to a small studio apartment. A 200 gaj plot (1800 sq ft) is a typical mid-size urban residential plot in north India.
Gaj to square yard equivalence
The defining identity:
1 gaj = 1 sq yd (exactly)100 gaj = 100 sq yd1 sq yd = 1 gajThe two terms are interchangeable. An Indian land deed listing “500 gaj” and an American real-estate listing of “500 sq yd” describe identical areas. The only difference is the language and cultural context of the document.
Gaj to square feet conversion
Because 1 yard = 3 feet, area scales by the square:
1 yd = 3 ft (length)1 sq yd = 9 sq ft (area)1 gaj = 9 sq ft100 gaj = 900 sq ftThe factor 9 is the easiest mental conversion in the entire system. When a Delhi listing quotes 250 gaj, that is 2250 sq ft — the kind of plot size a Bangalore listing would call “2250 sft.” The areas are identical; the units differ by a factor of 9.
The Indian government and the Bureau of Indian Standards have officially adopted the metric system. Land documents are supposed to use square metres or hectares. But traditional units — gaj, bigha, marla, kanal — survive everywhere because buyers, sellers, and local sub-registrars know them by feel. Modern sale deeds typically include both: “200 gaj (167.23 sq m)” is a common format.
Gaj in Indian real estate
The gaj is the everyday unit of north-Indian residential property. Typical plot sizes by tier of city:
- 50–100 gaj: small urban plot, single-family
- 200–300 gaj: standard residential plot (Delhi NCR suburbs)
- 500 gaj: large plot or builder floor
- 1000 gaj (0.21 acre): bungalow plot
- 2500–5000 gaj: farmhouse or institutional land
- 4840 gaj: exactly 1 acre
- 1 hectare: 11,960 gaj — agricultural scale
- Price per gaj: Rs 30k–Rs 300k typical (Delhi NCR, 2025)
Comparing prices across cities requires unit conversion. A Mumbai builder quoting Rs 25,000 per sq ft is asking 25,000 × 9 = Rs 225,000 per gaj. A Delhi developer quoting Rs 50,000 per gaj is asking 50,000 / 9 = Rs 5,556 per sq ft. The numbers look different but the conversion is just ×9 or ÷9.
Gaj, bigha, acre, and hectare
Larger Indian land units relate to the gaj by integer factors — but the bigha varies by state, so always check local definitions.
1 acre = 4840 gaj = 43,560 sq ft1 hectare ≈ 11,960 gaj = 2.471 acres1 bigha (UP) = 3000 gaj = 27,000 sq ft1 bigha (Rajasthan) ≈ 3025 gaj1 bigha (West Bengal) = 1600 gaj1 bigha (Bihar) = 3025 gajThe bigha is the most variable Indian land unit. Always confirm the local definition before signing. The UP standard (3000 gaj = 27,000 sq ft = 2508.4 m²) is the most common, but West Bengal’s 1600 gaj bigha (14,400 sq ft) is much smaller. The marla (Punjab/Haryana, 272.25 sq ft) and the kanal (5445 sq ft = 605 gaj) are even more localised.
When converting between sq ft and gaj for residential comparisons, the simplest mental check is: divide sq ft by 9 to get gaj, or multiply gaj by 9 to get sq ft. A 1620 sq ft apartment = 180 gaj. A 250 gaj plot = 2250 sq ft. The factor of 9 is exact and never changes.
Common gaj conversion mistakes
The word “gaj” historically meant a length unit (about 33–36 inches, varying by era). In modern real estate it means area = 1 sq yd. Confusing the two leads to enormous errors. Always check the document context. Property sale deeds and registration documents use the area meaning; very old land records (pre-British) may use the length meaning.
- Bigha varies by state: always confirm local definition
- Approximate 1 gaj = 0.83 m²: use 0.8361 for accuracy
- 1 acre = 4047 sq m: not 4000; conversion via gaj is exact
- Hectare ≠ acre: 1 ha = 2.471 acres = 11,960 gaj
- Sq yard ≡ gaj: identical, no factor
Gaj history and origin
The gaj traces back to the Mughal period (16th–18th centuries). Mughal land surveys used the Akbari gaj (about 33 inches) as a length unit; from this, the square gaj emerged as a natural area measure.
The British codified Indian land measurement in the 19th century. The colonial survey defined the area gaj as exactly 1 square yard (= 9 square feet = the British imperial yard squared), tying it to the British imperial system. That definition has held ever since the 1959 international yard agreement, which fixed the yard at exactly 0.9144 m. The Indian gaj inherited that exact value automatically.
Today the gaj survives partly because of inertia — deeds and documents have used it for two centuries — and partly because it suits the scale of urban residential plots. Square metres are awkward for a 200 sq yd plot (167.23 m²); the gaj gives a cleaner number that everyone in the local market recognises.
