Shotok to Square Feet (SFT): Convert Sotok, Satok & Decimal Without Mixing Linear Feet

1 Shotok = 435.6 square feet (sft), not linear feet. This guide explains shotok / sotok / satok / decimal spellings, the 1/100-acre legal definition, reverse sft-to-shotok math, and the values people actually search — including 5 sotok and 50 decimal.

Why “1 shotok to square feet” is the question that actually matters

In Bangladesh and West Bengal, sale ads, Facebook listings, and verbal negotiations almost always quote land in shotok (also spelled sotok, satok, shatak) or decimal. Bank files, mutation papers, and many English-language buyers then ask the same follow-up: how many square feet is that?

The legal answer is short:

1 Shotok = 435.6 square feet (sft / sqft)

That figure is not a round-number guess. It is exactly 1/100 of a statute acre. Because 1 acre = 43,560 sq ft:

43{,}560 \div 100 = 435.6 sq ft

If you only need the number for a deed in front of you, open the Shotok to Square Feet converter and type the value. This article explains the definition, the spellings searchers use, the “shotok to feet” mix-up, and the reverse conversion back from sft.

This is a conversion guide for the Bangladesh / West Bengal decimal (শতক) — not a replacement for the broader Shatak, Katha and Bigha unit survey or the Katha to Decimal walkthrough.

Shotok, sotok, satok, shatak, decimal: one unit, many spellings

All of the following names refer to the same area in standard Bangladesh and West Bengal land records:

Spelling you will see	Script / region	Same as 1 Shotok?
Shotok / Shotok	English ads, Facebook	Yes
Sotok	Spoken Bangla transliteration	Yes
Satok	Alternate English spelling	Yes
Shatak	Formal English / survey writing	Yes
Decimal / Disimil	Registry English, West Bengal	Yes
Shotangsho / Sotangso	Some West Bengal usage	Yes
শতক	Bangla deeds and khatian	Yes

Decimal and sotok are not two different sizes. If a listing says “50 decimal” and a neighbour says “50 sotok”, they are describing the same 50 units:

50 decimal = 50 sotok = 50 \times 435.6 = 21{,}780 sq ft

That identity is the answer to the common Bangla query “50 decimal koto sotok”: fifty equals fifty. Convert to square feet only when you need a bank, architect, or cross-border comparison — not because the two names differ.

Shotok to feet vs shotok to square feet

Search logs show “1 shotok to feet” as often as “1 shotok to square feet”. Those are not the same quantity.

Square feet (sft / sqft) is area. 1 shotok = 435.6 sft.

Linear feet is length. A shotok is not 435.6 feet long.

If the plot were a perfect square, each side would be:

\sqrt{435.6} \approx 20.87 linear feet

A 50 ft × 8.71 ft rectangle is also 435.6 sft — one shotok — with a completely different shape. Never treat “shotok to feet” as a length conversion. If you have side measurements instead of a shotok total, calculate area first with the plot-dimension land area guide, then divide square feet by 435.6.

Official formulas (both directions)

Shotok / decimal / sotok → square feet

SFT = Shotok \times 435.6

Square feet → shotok

Shotok = SFT \div 435.6

Shotok → square gaj (square yards)

1 square gaj = 9 sq ft, so:

Sq Gaj = Shotok \times 48.4

1 Shotok = 48.4 sq gaj

Shotok → square metres

1 Shotok = 435.6 \times 0.09290304 \approx 40.4686 m^2

Shotok → acre

Acre = Shotok \div 100

100 Shotok = 1 Acre = 43{,}560 sq ft

These acre and square-foot identities come from the same statute acre used in Gunter’s chain and link survey math. On a Gunter chain, 1,000 square links = 1 decimal / shotok.

Conversion table (values people actually type)

Shotok / sotok / decimal	Square feet (sft)	Square gaj	Square metres	Acre
1	435.6	48.4	40.47	0.01
2	871.2	96.8	80.94	0.02
3	1,306.8	145.2	121.41	0.03
5	2,178	242.0	202.34	0.05
10	4,356	484.0	404.69	0.10
13.5	5,880.6	653.4	546.33	0.135
33	14,374.8	1,597.2	1,335.47	0.33
50	21,780	2,420.0	2,023.43	0.50
100	43,560	4,840.0	4,046.86	1.00

5 sotok = 2,178 sft. That is the listing size behind many peri-urban “5 shotok” ads.

50 decimal = 21,780 sft = half an acre. It is also 50 sotok, not a different unit.

For katha instead of square feet: 50 decimal ≈ 30.25 katha on the standard Bangladesh / West Bengal katha of 720 sq ft. Use the Decimal to Katha converter when the deed is in katha, not sft.

Worked examples

Example 1 — “1 shotok to square feet”

1 \times 435.6 = 435.6 sft

Also 48.4 sq gaj, or about 40.47 m².

Example 2 — A 5 sotok roadside plot

5 \times 435.6 = 2{,}178 sft

If the usable rectangle is 54.45 ft × 40 ft, the product is also 2,178 sft. If a seller quotes 5 sotok but the site plan multiplies to 1,900 sft, the shortfall is about 0.64 shotok — ask before token money.

Example 3 — Reverse: 871.2 sft to shotok

871.2 \div 435.6 = 2 shotok

Example 4 — 50 decimal koto sotok, then sft

50 decimal = 50 sotok

50 \times 435.6 = 21{,}780 sft = 0.5 acre

Example 5 — Architect drawing in metres

A 1-shotok square is about 6.36 m × 6.36 m (because √40.47 ≈ 6.36). Most plots are not squares; convert total m² with:

Shotok = m^2 \div 40.4686

How shotok sits next to katha, bigha and acre

Stay on the Bangladesh / West Bengal ladder unless the deed names another state:

1 Katha = 720 sq ft ≈ 1.653 shotok

1 Bigha = 20 katha = 14,400 sq ft ≈ 33.06 shotok

1 Acre = 100 shotok = 43,560 sq ft ≈ 60.5 katha

Do not import Bihar katha, UP pucca bigha, or Nepal terai bigha into a Dhaka or Kolkata shotok calculation. Those sizes are documented separately in the Bigha to Acre regional breakdown.

Chittagong ganda / kani subdivisions are larger local ladders on top of the same 435.6 sq ft decimal. Convert ganda via the Gonda / Ganda land converter rather than inventing a new square-foot factor.

How to convert shotok to sft online

1.Open Shotok to Square Feet.

2.Enter the number from the deed, khatian, or listing — the tool treats shotok, sotok, satok, shatak and decimal as the same input.

3.Read square feet, square gaj and square metres together so a bank file and a Bangla ad can be compared.

4.Swap direction when you have a building plan in sft and need shotok for the mutation.

5.If you are buying and also need registry cost, estimate stamp / dalil charges with the dalil and stamp-duty calculator after you know the area.

ConverterDock runs the arithmetic in the browser. It does not replace a licensed surveyor, a khatian extract, or a lawyer’s reading of the plot schedule.

What to verify on the deed (not just the converter)

1.Name of the unit — শতক, decimal, shotok, and sotok should agree with 435.6 sq ft each. If the paper says katha, use 720 sq ft, not 435.6.

2.Survey series — CS / SA / RS / BS mouza maps can differ from a verbal “X shotok” claim. Match the khatian area, then convert.

3.Usable vs recorded area — Road, drain, or jointly owned passage may sit inside the recorded shotok.

4.Shape — Two plots of 3 shotok can have very different frontage. Convert to sft, then check length × width.

5.Jurisdiction — This 435.6 factor is the standard BD / WB decimal. Confirm locally if the property is outside that system.

Frequently asked questions

How many square feet in 1 shotok?

435.6 sft. The same number applies to 1 sotok, 1 satok, 1 shatak and 1 decimal in Bangladesh and West Bengal.

Is 1 shotok 435.6 feet long?

No. That is square feet of area. A square 1-shotok plot is only about 20.87 ft on each side.

What is 5 sotok in square feet?

2,178 sft.

50 decimal koto sotok?

50. Decimal and sotok are the same unit. In area terms, 50 decimal = 21,780 sft = half an acre.

How do I convert sft to shotok?

Divide by 435.6. Example: 4,356 sft ÷ 435.6 = 10 shotok.

Is shotok the same as katha?

No. 1 katha (BD / WB) = 720 sq ft ≈ 1.65 shotok. See Katha to Decimal.

Does this ratio work in Assam or Telugu records?

Assam uses bigha / katha / lessa; Telugu records use cent / kuncham / gunta. Cent happens to equal 435.6 sq ft as well (1/100 acre), but the names on the deed differ. Use the Assam or Telugu guides when the paperwork is not in shotok/decimal.

Key takeaways

1 shotok = 1 sotok = 1 satok = 1 shatak = 1 decimal = 435.6 sft = 48.4 sq gaj = 0.01 acre.

“Shotok to feet” in search almost always means square feet, not a length.

5 sotok = 2,178 sft. 50 decimal = 50 sotok = 21,780 sft.

Reverse with sft ÷ 435.6.

Convert with the Shotok to Square Feet calculator, then confirm the khatian before you pay.

*Figures above use the statute acre (43,560 sq ft) and the standard Bangladesh / West Bengal decimal. They are for measurement literacy, not a substitute for a registered survey or legal advice.*
