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 Square Metre? History, origin and usage

The square metre is the coherent SI derived unit of area, defined simply as the area of a square one metre on each side. It descends directly from the metre, which was introduced with the metric system in Revolutionary France in the 1790s.

It is the standard area unit worldwide for floor space, land, materials and scientific work, and is the base from which units like the hectare and square kilometre are built. Almost every country except a few uses the square metre for building and property area.

One square metre is about 10.76 square feet, and 10,000 square metres make one hectare. Its symbol, m squared, is the same in every language because it is a pure SI unit.

How to use this Chatak to Square Metre converter

Type a number into the Chatak field and the equivalent in Square Metre 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 Square Metre field to convert the other way (square metre 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 = 4.180637m²), 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-square metre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.

Indian land units can vary by state and local custom. This converter uses the most widely accepted standard value; always confirm against your local revenue records (patwari / tehsil) for legal transactions.
