What is a Chatak? History, origin and usage
The chatak (also spelt chhatak or chittak) is a small land unit long used in the Bengali-speaking region, including West Bengal and Bangladesh. The same word is also a traditional Bengali unit of weight (one-sixteenth of a seer), an example of one sub-division name reused across measurement systems.
As a land unit it is a fixed fraction of the rural Bengal katha, used for small plots and in property paperwork in West Bengal and Bangladesh. It lets buyers and sellers describe plots smaller than a single katha.
Sixteen chatak make one rural Bengal katha of 720 square feet, so one chatak is 45 square feet. The dual life of the word, as both an area and a weight, reflects its deep roots in Bengali commerce.
What is a Decimal? History, origin and usage
The decimal, also called satak or dismil, is a unit equal to one-hundredth of an acre that arose from British-era revenue surveys, which divided the acre into 100 equal parts. In Bengali-speaking areas it is satak, from shotangsho meaning 'hundredth part', the same idea that gives the unit its English name.
It is widely used across eastern India, especially Bihar, West Bengal, Odisha and Jharkhand, as well as in Bangladesh, for residential plots, agricultural land and government land records. Property advertisements and news reports in these regions still quote land in decimals.
One decimal is identical in size to one cent, both being one-hundredth of an acre (about 435.6 square feet). One hundred decimals therefore make exactly one acre.

- Both fields update live as you type — change either side to convert in that direction.
How to use this Chatak to Decimal converter
Type a number into the Chatak field and the equivalent in Decimal appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Decimal field to convert the other way (decimal to chatak). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 chatak = 0.1033058 decimal), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for chatak-to-decimal conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
