One acre equals 43,560 square feet everywhere in India — this figure never changes by state, since acre is an internationally standardised unit.

One acre equals 4,840 square yards (also called gaj).

One square yard equals 9 square feet.

One square meter equals approximately 10.76 square feet.

One hectare equals approximately 2.471 acres, and one acre equals approximately 0.4047 hectares.

A cent equals 1/100th of an acre, or 435.6 square feet — commonly used in Kerala, Tamil Nadu and parts of South India.

Yes, decimal and cent refer to the same unit — 435.6 square feet — the terms are used interchangeably in different regions.

One guntha equals 1,089 square feet, and 40 guntha make one acre — common in Maharashtra and Karnataka.

One ground equals 2,400 square feet — a unit used mainly in Tamil Nadu, especially Chennai.

An are equals 100 square meters, or about 1,076.4 square feet — a metric unit sometimes seen in agricultural records.

One kanal equals 20 marlas — this ratio is consistent across Punjab, Haryana, HP and J&K.

Under the standard Punjab measure, one kanal equals 5,445 square feet (605 square yards).

One kanal equals 605 square yards under the standard 66-inch karam measure used across most of Punjab.

One marla equals 272.25 square feet (30.25 square yards) under the standard Punjab revenue measure.

A sarsahi (also called square karam) is the smallest traditional Punjab unit — 30.25 square feet, and 9 sarsahi make one marla.

A karam is a length unit, standardised at 5.5 feet (66 inches) in most of Punjab, though some districts historically used 54, 57.5 or 60 inches.

In Punjab’s revenue system, one pucca bigha equals 4 kanals, or 2,420 square yards — different from bigha in UP, Bihar or Rajasthan.

One acre (killa) equals 8 kanals under the standard Punjab measure.

One acre equals 2 pucca bigha in the Punjab revenue system.

A biswa equals 4 marla, or 1,089 square feet, in the standard Punjab measure — 5 biswa make one kanal.

A murabba is the largest traditional Punjab land unit, equal to 25 acres (25 killas) — used mainly for large agricultural holdings.

Yes — in some older, non-consolidated areas of Amritsar, Gurdaspur, Hoshiarpur and the former Kapurthala state, a different karam length was historically used, changing the exact square footage of a marla and kanal in those specific pockets. Always verify locally.

Because some parts of Punjab historically used a smaller karam (54–60 inches instead of 66 inches), producing a smaller marla in square feet. Always ask which measure the seller’s papers use.

Urban GMADA-developed plots are typically registered in square yards, while rural land in revenue records is recorded in kanal-marla — check your specific sale deed.

GMADA allots residential, commercial and industrial plots primarily in square yards, even though pooled agricultural land is measured in acres/kanals before development.

Banks typically value property in square feet or acres for loan sanction — local-unit paperwork (kanal-marla, bigha) needs to be converted to match.

Registry transfers legal ownership via a registered sale deed; mutation (“intkal”) is the separate process of updating the revenue record (jamabandi) to reflect the new owner. Both are needed.

Stamp duty is calculated on area × the applicable circle rate — converting to the correct unit avoids under-paying (which can cause legal issues) or over-paying stamp duty.

No — the sale deed should state one consistent unit matching the actual measured area. Mixing units without clear conversion can cause disputes later.

Construction quotes in India are almost always given per square foot of built-up or super built-up area, regardless of what unit the underlying plot was sold in.

GMADA residential plots are commonly listed as 100, 125, 150, 200 or 300 square yards, depending on the sector and scheme.

UP bigha figures are commonly cited around 3,025 square yards, but the exact value can vary by district — always confirm locally rather than assuming a fixed number.

A katha is a sub-unit of bigha, commonly cited around 720 square feet in West Bengal, though the exact figure can vary by district and local practice.

A nali is a hill-region unit commonly cited around 2,160 square feet, though this varies across Uttarakhand’s different districts.

A vigha in Gujarat is commonly cited in the 17,000–19,500 square feet range, with regional variation — verify with local revenue records.

No — bigha size varies significantly between Punjab, UP, Bihar, West Bengal, Rajasthan and Assam. Never assume one state’s bigha value applies to another.

Acre is more common in everyday real estate and banking use, while hectare is the standard unit in most official government land records and Survey of India maps.

Because units like bigha, biswa, and marla are not nationally standardised — they vary by state, district, and sometimes revenue circle. This tool uses the common Punjab-region values; always verify locally for legal use.

Use online converters like this one for quick estimates and planning, but always confirm final figures against the Patwari record, sale deed, or a licensed surveyor before signing legal or financial documents.

Get a physical survey done by a licensed surveyor or the local Patwari, and cross-check it against your sale deed and revenue record — don’t rely solely on any calculator, including this one.
