Indian Land Area Units, Explained
India uses a mix of metric units (Square Meter, Hectare) and traditional local units (Guntha, Bigha, Katha, Cent, Ankanam, Ground) in property documents, revenue records, and everyday real estate conversations. The metric and imperial units are fixed mathematical ratios that never change. The traditional units — Guntha, Bigha, and Katha in particular — were set locally by each state and can differ significantly from one state to another.
Fixed Units (Same Everywhere)
- 1 Square Meter = 10.7639 sq ft
- 1 Square Yard (Gaj) = 9 sq ft
- 1 Acre = 43,560 sq ft = 4,046.86 sq m
- 1 Hectare = 107,639.10 sq ft = 2.471 acres
- 1 Cent = 435.6 sq ft (1/100 acre — Kerala, Tamil Nadu, parts of Karnataka & Andhra Pradesh)
- 1 Ankanam = 72 sq ft (Andhra Pradesh & Telangana, small residential plots)
- 1 Ground = 2,400 sq ft (Tamil Nadu, especially Chennai)
Region-Dependent Units
Guntha / Gunta
1 Guntha = 1,089 sq ft = 101.17 sq m = 1/40 acre.
Fairly consistent across the states that use it — Karnataka, Maharashtra, Andhra Pradesh, and Telangana all treat 1 Guntha (also spelled Gunta) as 1,089 sq ft, a 33 ft × 33 ft plot.
Bigha
1 Bigha ranges from 14,400 sq ft (West Bengal) to ≈27,225 sq ft (Uttar Pradesh / Bihar).
Bigha is genuinely different by state — West Bengal's Bigha is roughly half of Uttar Pradesh's or Bihar's Pucca Bigha, despite sharing the same name. Use the regional standard selector in the calculator above, or see the state-specific guides below.
Katha
1 Katha ranges from 720 sq ft (West Bengal) to ≈1,361 sq ft (Bihar / Uttar Pradesh).
Katha follows the same regional split as Bigha — twenty Katha make one Bigha in both Bengal and Bihar/UP, but the underlying sq-ft value differs by state.

Frequently Asked Questions
How many square feet is 1 Guntha?
1 Guntha = 1,089 sq ft = 101.17 sq m. This is exactly 1/40th of an acre (a 33 ft × 33 ft plot) and is used mainly in Karnataka, Maharashtra, Andhra Pradesh, and Telangana land records.
How many square feet is 1 Acre?
1 Acre = 43,560 sq ft = 4,046.86 sq m = 40 Guntha = exactly 100 Cent = 4,840 sq yd.
How many square feet is 1 Bigha?
Bigha has no single fixed value across India — it is approximately 14,400 sq ft in West Bengal, 27,225 sq ft in Uttar Pradesh, and 27,220 sq ft in Bihar. Always confirm your state's exact figure before using it for any transaction.
How many square feet is 1 Katha?
Katha also varies by state: 720 sq ft in West Bengal, and approximately 1,361 sq ft in Bihar and Uttar Pradesh (where it is often called Katha or Biswa locally). Confirm the local figure with your revenue department before relying on it.
What is 1 Cent in square feet?
1 Cent = 435.6 sq ft = 40.47 sq m. This is exactly 1/100th of an acre and is the standard small-plot land unit in Kerala, Tamil Nadu, and parts of Karnataka and Andhra Pradesh.
How many square feet is 1 Ground in Tamil Nadu?
1 Ground = 2,400 sq ft = 223.03 sq m. Ground is the standard land unit used across Tamil Nadu, especially in Chennai real estate, roughly equal to a 40 ft × 60 ft plot.
What is 1 Ankanam in square feet?
1 Ankanam = 72 sq ft = 6.69 sq m. Ankanam is a traditional unit used in Andhra Pradesh and Telangana, mainly for small residential plots and older property records.
Is Guntha the same as Gunta?
Yes. "Guntha" and "Gunta" are spelling variants of the same land unit — both equal 1,089 sq ft = 1/40 acre. Karnataka land records tend to use "Gunta"; Maharashtra, Andhra Pradesh, and Telangana more often use "Guntha."
Why does Bigha mean a different area in different states?
Bigha was never standardized under British or post-independence law the way the metric system was — each princely state and later each state government fixed its own local Bigha based on regional farming plot sizes. As a result, West Bengal's Bigha (≈14,400 sq ft) is roughly half of Uttar Pradesh's or Bihar's Pucca Bigha (≈27,225 sq ft), even though both are called 'Bigha'.
