Indian land units (Bigha, Marla, Killa, etc.) vary by state. This tool uses the most common standardized values - Bigha (Pucca, North India) = 27,225 sq.ft, Gunta = 1,089 sq.ft, Ground (TN) = 2,400 sq.ft, Kanal = 5,445 sq.ft (Punjab), Marla = 272.25 sq.ft, Killa = 1 acre, Cent = 1/100 acre. For property registration, always confirm the local definition with your sub-registrar or village patwari.

Area Converter verstehen
Area conversion is one of the highest-value converter pages for Indian users because land and property units vary dramatically by region. A flat listing in Mumbai may quote carpet area in square feet, a farm plot in Punjab may be discussed in killa, kanal or marla, a Tamil Nadu residential plot may be quoted in grounds or cents, and official land records often use hectares or acres. Buyers, sellers, farmers, brokers, civil engineers and lawyers all need accurate area conversion before comparing prices or documents.
This converter supports international metric and imperial units plus common Indian land units such as bigha, biswa, gunta/guntha, ground, kanal, marla, killa and cent. The important caution is that some traditional units are not uniform across India. A bigha in Uttar Pradesh is not the same as a bigha in West Bengal, Madhya Pradesh or Gujarat. This page uses common standardised values and clearly warns users to verify local definitions with a registrar, patwari, village office, seller or survey document before making legal or financial decisions.

So funktioniert Area Converter
Area units are linear - each has a fixed factor to the SI base, the square meter. To convert, we multiply by the source factor, then divide by the target factor. Indian units like Bigha and Marla vary by state, so this tool uses the most common standardized values: Bigha (Pucca, North India) = 2,529.29 m² ≈ 27,225 sq.ft, Gunta = 101.17 m², Kanal = 5,445 sq.ft (Punjab), Marla = 272.25 sq.ft, Killa = 1 acre, Cent = 1/100 acre. If your local definition differs, double-check with your registrar or the seller.

Wie Area Converter zum Ergebnis kommt
The converter uses square metre as the central base unit. Each supported unit has a fixed factor to square metres. To convert 1200 sq ft to sq m, multiply by 0.09290304 and get 111.48 sq m. To convert 1 acre to sq ft, convert through square metres or use the exact reference: 1 acre = 43,560 sq ft = 4046.8564224 sq m.
Area conversion is not the same as length conversion. If 1 metre = 3.28084 feet, then 1 square metre = 3.28084² = 10.7639 square feet. Squaring the linear conversion factor is why area numbers change more dramatically. This is a common source of mistakes when students or buyers try to convert plot sizes manually.
For Indian land units, legal accuracy depends on the local definition. Bigha is the biggest caution: North Indian pucca bigha is around 27,225 sq ft, West Bengal bigha around 14,400 sq ft, and several states use other values. Gunta/guntha is widely treated as 1089 sq ft and 40 guntas = 1 acre. Ground in Tamil Nadu is 2400 sq ft. Cent is 435.6 sq ft and 100 cents = 1 acre.

Agricultural land: 2 acres to guntas
1 acre = 40 guntas. Therefore 2 acres = 80 guntas. In Karnataka and Maharashtra land discussions, this is a very common farmer and broker conversion.
Tamil Nadu plot: 1 ground to square feet and cents
1 ground = 2400 sq ft. 1 cent = 435.6 sq ft. So 1 ground = 2400 / 435.6 = 5.51 cents approximately. Chennai plot listings commonly use ground.

- Confusing carpet area, built-up area and super built-up area.
- Using approximate broker conversions for legal documents.
- Mixing acre and hectare. 1 hectare is 2.471 acres, not 1 acre.

Fragen zu Area Converter
How many square feet in a Bigha?
It depends on the state. In most of North India (UP, Bihar, Rajasthan), 1 Pucca Bigha ≈ 27,225 sq.ft (2,529.29 sq.m). West Bengal Bigha ≈ 14,400 sq.ft. Madhya Pradesh Bigha ≈ 12,000 sq.ft. Gujarat Bigha ≈ 17,427 sq.ft. Always confirm with the local registrar.
How many square feet in 1 acre?
1 acre = 43,560 sq.ft = 4,046.86 sq.m = 0.4047 hectare = 4,840 sq.yd. In Punjab/Haryana, 1 acre also equals 1 Killa or 8 Kanals.
What is a Gunta or Guntha?
Gunta (also Guntha) is a unit common in Maharashtra, Karnataka and Andhra Pradesh. 1 Gunta = 1,089 sq.ft = 101.17 sq.m. 40 Guntas = 1 acre.
What is a Ground in Tamil Nadu?
1 Ground = 2,400 sq.ft ≈ 222.97 sq.m. It's the most common unit for plot sizes in Chennai and other Tamil Nadu cities.
What is a Cent?
Cent is widely used in Tamil Nadu, Kerala and Andhra Pradesh. 1 Cent = 1/100 acre = 435.6 sq.ft ≈ 40.47 sq.m. So 100 Cent = 1 acre.
What's the difference between Kanal and Marla?
Both are used in Punjab and Haryana. 1 Kanal = 20 Marlas = 5,445 sq.ft = 605 sq.yd ≈ 505.86 sq.m. So 1 Marla ≈ 272.25 sq.ft.
How many sq.ft in a hectare?
1 hectare = 10,000 sq.m = 107,639.1 sq.ft = 2.47105 acres. Hectare is the official metric area unit used in agriculture worldwide.
Why do Bigha and Marla values vary by state?
Indian land units date to pre-British and Mughal-era surveys. Each region historically used different rod and chain lengths, and those local conventions were locked into state revenue records. Always verify the unit definition with the seller, sub-registrar office, or village patwari.
Convert with confidence
Conversion math is exact for unit families that share a base - every length unit can be expressed in metres, every weight in kilograms, every temperature in kelvin. The only real decisions are precision (how many decimals to display) and rounding (banker's rounding vs round-half-up). This converter exposes both. For currencies and crypto we pull live rates because they change every minute; for everything else the math works offline.
Indian land units (gaj, ground, bigha, acre, hectare) are wired into the area converter alongside global ones - useful for property listings and government records. The MB-to-GB converter handles the decimal-vs-binary distinction (1 GB = 1,000 MB in storage marketing, but operating systems display 1 GiB = 1,024 MiB) so you stop wondering why your '2 TB drive' shows up as 1.81 TB in Windows.
