The Cadastral Architecture of Land Measurement in Bangladesh

In Bangladesh, land ownership records are administered by the Ministry of Land (Bhumi Montronaloy) through Assistant Commissioner (Land) / AC Land offices, Sub-Registries, and Upazila Land Offices. Through the online E-Mutation and E-Porcha platforms, citizens now access historical survey records (Cadastral Survey / CS, State Acquisition / SA, Revisional Survey / RS, and City/BS Survey) digitally.

Throughout Bangladesh, official title deeds (Dalil) and record-of-rights (Khatian) quantify land in Acres and Decimals. In everyday property discussions, Shatak, Katha, and Bigha are also widely used:

  • Shatak / Decimal (Shotangsho): Exactly 1/100th of an acre = 435.60 square feet (48.4 Gaj or 40.4686 m²). This is the base benchmark of all rural farmland valuation.
  • Chhatak: The smallest traditional subdivision = 1/16th of a Katha = 45 square feet (5 Gaj or 4.18 m²).
  • Katha: 16 Chhataks = 720 square feet (80 Gaj or 66.89 m²). In urban Dhaka (under RAJUK jurisdiction) and Chittagong (CDA), residential plots in schemes like Uttara, Purbachal, Mirpur, and Bashundhara are officially laid out in Kathas (typically 3 Katha, 5 Katha, or 10 Katha plots). 1 Katha equals approximately 1.6529 Decimals.
  • Bigha (Standard): Standardized under the Bengal Tenancy Act as exactly 20 Kathas = 14,400 square feet (1,600 Gaj = 33 Decimals or 1,337.8 m²). Note that an acre contains approximately 3.025 Bighas.
  • Kani & Ganda: In Chittagong, Cox's Bazar, and Sylhet divisions, land records cite Kanis. 4 Kora = 1 Ganda (864 sq ft). 20 Gandas = 1 Kani = 17,280 square feet (about 39.67 Decimals or 1.2 Bighas).

Original Worked Examples for Bangladesh Property

Scenario 1 • Dhaka RAJUK Plot

Buying a 5-Katha Plot in Purbachal, Dhaka

A family purchasing a residential plot in Purbachal New Town wants to determine the total square footage and Decimal area.

Formula: Area (sq ft) = Katha × 720
Calculation: 5 × 720 = 3,600 sq ft
Decimals: 3,600 ÷ 435.6 = 8.264 Shatak (400 Gaj)

Result: 5 Kathas equals 3,600 square feet (approx 8.26 Shatak or 400 Gaj).

Scenario 2 • Bogura Agricultural Farmland

Converting 45 Shatak (Decimals) to Kathas & Bighas

A paddy farmer in Bogura inherits 45 decimals of fertile agricultural land.

Total Sq Ft = 45 × 435.6 = 19,602 sq ft
Kathas = 19,602 ÷ 720 = 27.225 Katha
Bighas = 45 ÷ 33 = 1.3636 Bighas (1 Bigha, 7.225 Katha)

Result: 45 Shatak equals 1.36 Bighas (27.23 Kathas or 19,602 sq ft).

Scenario 3 • Sylhet Rural Homestead

Converting 3 Kanis to Decimals and Square Feet

A Non-Resident Bangladeshi (NRB) from the UK verifies ancestral family land in Sylhet recorded as 3 Kanis.

1 Kani = 17,280 sq ft ≈ 39.67 Decimals
Total Sq Ft: 3 × 17,280 = 51,840 sq ft
Decimals: 51,840 ÷ 435.6 = 119.01 Decimals (1.19 Acres)

Result: 3 Kanis equals approximately 119 Decimals (51,840 sq ft).

Scenario 4 • Gazipur Garment Factory Pad

Converting a 2-Acre Industrial Parcel to Bighas

An export textile mill in Gazipur acquires 2 acres for an effluent treatment plant.

1 Acre = 3.025 Bighas = 100 Decimals
Calculation: 2 × 3.025 = 6.05 Bighas
Total Sq Ft: 2 × 43,560 = 87,120 sq ft

Result: 2 Acres equals 6.05 Bighas (87,120 sq ft or 200 Decimals).

Scenario 5 • Dhanmondi Residential Apartment

Converting a 1,800 Sq Ft Flat to Square Metres

A structural engineer reviews floor load ratings for an apartment in Dhanmondi, Dhaka.

Formula: Sq Metres = Sq Ft × 0.092903
Calculation: 1,800 × 0.092903 = 167.23 m²

Result: 1,800 square feet equals 167.23 square metres.

Scenario 6 • Small Land Parcel

Converting 8 Chhataks to Square Feet

A boundary adjustment between two homes involves a transfer of 8 Chhataks.

1 Chhatak = 45 sq ft (5 Gaj)
Calculation: 8 × 45 = 360 sq ft (0.5 Katha)

Result: 8 Chhataks equals exactly 360 square feet (40 Gaj or half a Katha).

Frequently Asked Questions: Bangladesh Land Measurement

One Decimal (known as Shatak or Shotangsho) equals exactly 435.60 square feet (48.4 Gaj / square yards or 40.4686 square meters). Because 100 decimals make one acre (43,560 sq ft), 1 decimal is 1/100 of an acre.
In Bangladesh, 1 standard Katha equals exactly 720 square feet (80 Gaj or 66.89 square meters). It is composed of 16 Chhataks (each 45 sq ft) and equals approximately 1.6529 Decimals.
In Bangladesh, 1 standard Bigha contains 20 Kathas, which equals exactly 33 Decimals (or 33.058 Decimals in precise mathematical terms). In square feet, 1 Bigha equals 14,400 square feet (1,600 Gaj).
There are approximately 3.025 Bighas in one Acre in Bangladesh (43,560 sq ft ÷ 14,400 sq ft = 3.025). This is significantly different from North India, where an acre equals 1.6 or 2 Bighas.
A Kani is a traditional land measurement unit used in parts of Bangladesh. A commonly referenced Kani contains 20 Gandas and equals 17,280 square feet, or about 39.67 Decimals. Check the applicable land record for the local convention.
A Chhatak is the fractional unit of a Katha. 1 Katha contains 16 Chhataks. Therefore, 1 Chhatak equals 720 ÷ 16 = 45 square feet (5 Gaj or 4.18 square meters).
In planned townships under RAJUK (Capital Development Authority of Dhaka), residential plots are specified in Kathas: 3 Katha plots (2,160 sq ft), 5 Katha plots (3,600 sq ft), and 10 Katha plots (7,200 sq ft). Building construction approvals also mandate square metre specifications.
