4 decimals is enough for property registration. Increase to 6 for surveying and engineering work, or drop to 0-2 for casual conversion.

3

Use the reference table

The Reference tab below shows cents converted to m², ft², acres, ground (Tamil Nadu), and guntha (Karnataka). All Indian regional units in one place.

Quick rule: 100 cents = 1 acre. 1 cent ≈ 40.5 m² ≈ 436 sq ft.
Cent vs ground: 1 cent ≈ 18.15% of 1 ground (Tamil Nadu). 1 ground = 2,400 ft² ≈ 5.5 cent.

Formulas

The cent is one-hundredth of an acre. The acre is defined as 4,840 square yards, which gives the cent exactly 43.56 ft² × 10 = 435.6 ft². The metric equivalent follows from the international yard definition (1 yd = 0.9144 m exactly).

Cent to m²
$$ \text{m}^2 = \text{cent} \times 40.4686 $$
Exact factor. 1 cent = 1/100 acre = 43.56 ft² = 40.46856 m² (rounded to 6 decimals: 40.4686).
m² to cent
$$ \text{cent} = \text{m}^2 \times 0.0247105 $$
Reciprocal: 1 m² = 1/40.4686 cent ≈ 0.0247105 cent. A 100 m² plot is about 2.47 cents.
Derivation from acre
$$ 1\,\text{acre} = 100\,\text{cent} = 4{,}046.856\,\text{m}^2 $$
The acre is exactly 4,840 yd² = 43,560 ft². Dividing by 100 gives 1 cent = 43.56 ft² = 40.4686 m².
Cent to ft²
$$ \text{ft}^2 = \text{cent} \times 435.6 $$
Useful for cross-checking against US-style listings. 1 cent = 435.6 ft² exactly (43.56 × 10).
Cent to ground (Tamil Nadu)
$$ 1\,\text{ground} = 2{,}400\,\text{ft}^2 = 5.51\,\text{cent} $$
In Tamil Nadu, urban plots are often quoted in ground (2,400 ft²). 1 cent ≈ 0.1815 ground; 1 ground = 5.51 cent.
Cent to guntha (Karnataka, Maharashtra)
$$ 1\,\text{guntha} = 1{,}089\,\text{ft}^2 = 2.5\,\text{cent} $$
In Karnataka, Maharashtra, and parts of Andhra Pradesh, rural plots are quoted in guntha (1,089 ft²). 1 cent = 0.4 guntha; 1 guntha = 2.5 cent.

Cent to Square Meter Conversion in Indian Real Estate

A cent is an Indian land area unit equal to exactly 40.4686 square meters or 435.6 square feet. It is one-hundredth of an acre — hence the name, from Latin centum meaning 100. The unit is dominant in Kerala and widely used in Tamil Nadu, Karnataka, Andhra Pradesh, and Telangana. A typical urban house plot in Kerala runs 5 to 10 cents (about 200 to 400 m²), while rural agricultural plots can run into the hundreds.

Converting cent to square meters matters for property registration, comparing listings across states with different traditional units, and reading metric-only land surveys.

What is a cent in land area?

A cent is exactly 1/100 of an acre. Since the international acre is 4,046.8564224 m², a cent is 40.46856422 m² — rounded to four decimals, 40.4686 m². The same value in imperial units is 435.6 ft². The cent is not an SI or ISO unit; it is a regional convention codified in Indian state land-revenue rules and property registrations.

The cent sits between the small unit of square yard (0.836 m²) and the larger acre (4,047 m²). For typical residential plots it produces convenient numbers: 1-10 cents covers most single-home parcels, and 25-100 cents covers larger compounds.

Did you know

The cent is also used as a land area unit in parts of Sri Lanka, the Bahamas, and a few Caribbean islands — anywhere the British acre system landed and small plot sizes pushed administrators toward a 100-part subdivision. Cent in India almost always refers to land; the cent monetary unit (1/100 dollar) is unrelated.

Cent to square meter math

One multiplication does the job. cent × 40.4686 = m². For the reverse, m² × 0.0247105 = cent. Both factors are exact derivations from the 1959 international yard agreement, which fixed 1 yd = 0.9144 m and hence 1 acre = 4,046.8564224 m².

For a 5-cent house plot: 5 × 40.4686 = 202.343 m². For a 200 m² apartment plot: 200 × 0.0247105 = 4.9421 cents. Property registration documents typically quote three or four decimals.

Cent reference values
1 cent = 40.4686 m² = 435.6 ft²
100 cents = 1 acre = 4046.86 m²
2.5 cents = 1 guntha = 101.17 m²
5.51 cents = 1 ground = 222.97 m²

Origin of the cent land unit

The cent came into Indian usage through British colonial land administration. The acre had been the unit of agricultural land assessment across the Empire, and revenue surveyors needed a smaller unit for residential plots and partial holdings. Dividing the acre into one hundred parts produced the cent — a unit small enough for urban use and arithmetically clean.

After independence, the cent remained the default in regions where the colonial-era acre-based survey records were dense — particularly the former Madras Presidency, which covered most of present-day Tamil Nadu, Kerala, and Karnataka. Plot deeds and revenue records carried forward in cents because every existing document was already in those units.

Cent vs ground vs guntha

Three regional Indian land units overlap. The cent is dominant in Kerala. Tamil Nadu adds the ground (2,400 ft² = 222.97 m² = 5.51 cents) for urban Chennai plots. Karnataka, Maharashtra, and Andhra Pradesh use the guntha (1,089 ft² = 101.17 m² = 2.5 cents) for rural plots.

Using cent in property registration

Indian property deeds in cent-using states record area in cents with three or four decimal places. A plot might be registered as "7.832 cents" or "12.5 cents." Stamp duty and registration fees are calculated against the deed area at the government guideline price (per cent) for the locality.

When buying or selling, always cross-check the deed area against the survey department records. Encroachments, partition agreements, and historical mis-records can mean the deed area and the surveyed area differ. The state revenue department issues a Pokkuvaravu (Kerala) or patta (Tamil Nadu) showing the official surveyed area.

Tip

When viewing plots, the dimensions on the boundary stones are usually in meters or feet, not cents. Use this calculator to convert from meter dimensions back to cents. A 14 m × 14.5 m plot = 203 m² = 5.014 cents.

Cent vs metric units

India officially uses the metric system, and modern survey maps and government land records often record area in square meters or hectares alongside the traditional unit. The are (100 m²) is the closest small metric unit; 1 cent ≈ 0.4047 are. The hectare (10,000 m²) equals 247.105 cents.

  • 1 cent = 40.4686 m² = 435.6 ft² = 0.4047 are
  • 1 acre = 100 cent = 4,046.856 m² = 0.4047 hectare
  • 1 hectare = 247.105 cent = 10,000 m² = 2.471 acre
  • 1 guntha = 2.5 cent = 1,089 ft² = 101.17 m²
  • 1 ground = 5.51 cent = 2,400 ft² = 222.97 m²
  • 1 are = 100 m² = 2.471 cent
  • 1 square yard = 0.836 m² = 0.0207 cent

Cent usage by Indian state

Kerala leads in cent dominance: almost every residential plot in the state is quoted in cents, from urban Kochi apartments to rural Idukki hill plots. Tamil Nadu mixes cent (rural, smaller plots) with ground (Chennai metropolitan plots). Karnataka leans on guntha for agricultural plots and uses cent in older urban records. Andhra Pradesh and Telangana lean toward square yards in urban registrations while retaining the cent for smaller rural transactions.

Outside the South, the cent is essentially unused. Northern states use bigha (varies by state, 1,500-2,500 m²), biswa (1/20 bigha), and marla (about 25 m²). Mumbai and Gujarat use square meter and hectare for registration, with vernacular references to gaj (square yard) in older deeds.

Common cent conversion mistakes

The most frequent error is conflating cent with square yard. A plot quoted as "100 yard" in Andhra Pradesh is 100 square yards (83.6 m²) — about 2.07 cents, not 100 cents (= 1 acre). Always confirm the unit before doing the math; a yard-vs-cent mistake produces a 50× error.

Don't round the conversion factor too aggressively

Some sources cite 1 cent = 40.46 m² or 40.47 m². For registration purposes, use the four-decimal value 40.4686 m² (or more decimals if available). A 100-cent plot rounded to 40.46 m²/cent is off by 0.6 m² — small per cent, but for large agricultural parcels the error adds up.

A third common slip is mixing cent (Indian, 1/100 acre) with the cent as a currency abbreviation. They are unrelated. The land unit is always area; the currency cent appears on Indian banking interfaces translated as "paise" anyway.

FAQ

1 cent = 40.4686 m² (exact). The cent is one-hundredth of an acre, so 100 cents = 1 acre = 4,046.86 m². A typical 5-cent house plot in Kerala is about 202 m² or 2,178 ft².
100 cents = 1 acre. The cent gets its name from the Latin centum (100), reflecting this exact ratio. Larger rural plots in South India are often quoted in cents up to a few hundred.
The cent is used in Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, and parts of Telangana. It is most dominant in Kerala, where almost all residential and small commercial plots are quoted in cents. North India uses bigha and marla instead.
1 cent = 435.6 ft². The conversion is exact: 43,560 ft² (1 acre) ÷ 100 = 435.6 ft². A 10-cent plot is 4,356 ft², roughly the footprint of a large single-family home with a garden.
1 cent = 0.4 guntha, or 1 guntha = 2.5 cents. Guntha is the standard rural unit in Karnataka and Maharashtra. 40 guntha = 1 acre = 100 cent. The two systems are convertible without rounding.
1 ground = 5.51 cents = 2,400 ft². Ground is a Tamil Nadu urban-plot unit, especially common in Chennai and Coimbatore. A 1-ground plot is roughly a small detached-home parcel.
Urban Kerala house plots are typically 5-10 cents (200-400 m²). Larger suburban plots run 15-25 cents. Rural plots can be much larger — 50 cents to several acres. Apartment plots inside cities are sometimes as small as 3 cents.
South Indian land records during British colonial administration adopted the acre system, with the cent (1/100 acre) as a sub-unit. Kerala's small-plot economy made the cent the practical default. The unit stuck even after independence and the metric transition.
