Decare vs Chatak: which is bigger?
A decare is the larger unit: one decare equals 239.198 chataks. Put another way, you need 239.198 chataks to make a single decare.
What is a Decare? History, origin and usage
The decare is a metric land unit of 1,000 square metres, equal to 10 ares or one-tenth of a hectare. It corresponds to the modern metric dunam, whose name comes from the Ottoman Turkish donum (from donmek, 'to turn'), originally the area a team of oxen could plough in a day.
The decare and its dunam equivalent are used in Norway, Turkey and parts of the Balkans, while the metric dunam of 1,000 square metres adopted in 1928 is standard in Israel and Palestine. It is a convenient mid-size unit between the are and the hectare.
One decare equals one metric dunam, exactly 1,000 square metres, and ten decares make one hectare. The Ottoman dunam was a regional cousin of the English acre and the Greek stremma, all rooted in a day's ploughing.
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.

How to use this Decare to Chatak converter
Type a number into the Decare field and the equivalent in Chatak 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 Chatak field to convert the other way (chatak to decare). 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 daa = 239.198 chatak), 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 decare-to-chatak conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
