Satak: Acre to Satak and Satak to Bigha

1 acre is 100 satak. A satak (শতক, also spelt shatak or sotok) is one hundredth of an acre, which is 435.6 sq ft. It is the same size as a decimal or a cent.

What is a satak?

Satak is the Bengali name for the decimal. The word comes from "shat", meaning a hundred, because 100 satak make 1 acre. In West Bengal, the khatian and record of rights show land in acre and decimal, and people read the decimal figure as satak. The same unit is called decimal or dismil in Bihar, Jharkhand and Odisha, and cent in the south.

Since it is tied to the acre, the satak is fixed. It does not change from district to district, unlike the bigha and katha.

1 satak in other units

• 1 satak = 435.6 sq ft
• 1 satak = 48.4 sq yd (gaj)
• 1 satak = 40.47 sq m
• 1 satak = 9.68 chatak
• 1 satak = 0.605 katha (West Bengal)
• 1 satak = 0.0303 bigha (West Bengal)

Acre to satak and satak to acre

The rule is simple: multiply acres by 100 to get satak, and divide satak by 100 to get acres.

So 33 satak is 0.33 acre, and 150 satak is 1.5 acre. See acre to decimal for any value.

Satak to bigha and katha (West Bengal)

West Bengal uses a uniform chain: 1 bigha = 20 katha = 320 chatak = 14,400 sq ft. Against this chain:

• 1 bigha = 33.0579 satak
• 1 katha = 1.6529 satak
• 1 satak = 0.605 katha, or about 9.68 chatak
• 1 acre = 3.025 bigha = 60.5 katha

Example: a field of 50 satak is 21,780 sq ft. Divide by 14,400 and you get 1.5125 bigha, or 1 bigha and about 10.25 katha. The satak to katha converter does this for any number.

Outside Bengal, the bigha and katha change size, so satak to bigha changes too. In Uttar Pradesh, a pucca bigha of 27,225 sq ft is 62.5 satak. Check the bigha page for other regions.

Satak to hectare

1 hectare = 247.11 satak, and 1 satak = 0.004 hectare. Newer documents sometimes show area in hectares, so this helps you match old and new papers.

How to convert satak

1. Satak to square feet: multiply by 435.6. Example: 6 satak = 2,613.6 sq ft.
2. Satak to square yard: multiply by 48.4. Example: 6 satak = 290.4 sq yd.
3. Satak to katha (West Bengal): multiply by 0.605. Example: 6 satak = 3.63 katha.

Reading satak in a record

A record may show a plot as 0.0825 acre. Move the decimal point two places to the right and you get 8.25 satak. That is 8.25 x 435.6 = 3,593.7 sq ft, or 4.99 katha on the West Bengal measure. In the same way, 1.07 acre is 107 satak.

When a family divides land, it is easier to split satak than bigha and katha, because satak is a plain decimal number. For example, 120 satak shared among three heirs is 40 satak each, which is 17,424 sq ft or 24.2 katha each.

Plot sizes in satak

• A 20 ft by 30 ft plot is 600 sq ft, about 1.38 satak.
• A 30 ft by 40 ft plot is 1,200 sq ft, about 2.75 satak.
• A 33 ft by 66 ft plot is exactly 5 satak (2,178 sq ft).

Practical tips

• Your khatian on Banglarbhumi shows area in acre and decimal. Treat the decimal as satak.
• Small Kolkata plots are often in katha and chatak. Convert them to satak before you compare with the record.
• For a sale or partition, confirm the area with the amin or the local land revenue office and check the record of rights. See the West Bengal guide.
