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 Lessa? History, origin and usage

Lessa (also spelt lecha, locha or losha) is a small traditional land unit of Assam and neighbouring parts of north-east India. Its precise origin is not well recorded, but it long predates metrication and forms the base of the Assamese bigha-katha-lessa ladder.

It is used in Assam for fine measurement of small plots, where 20 lessa make one katha and, because the Assam bigha equals five katha, 100 lessa make one bigha. The unit was officially superseded by metric measures in the mid-20th century but survives in local land dealings.

One lessa is 144 square feet, a tidy 12-foot by 12-foot square. It can be subdivided further into still smaller traditional units such as powas and kanis.

How to use this Chatak to Lessa converter

Type a number into the Chatak field and the equivalent in Lessa 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 Lessa field to convert the other way (lessa 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 = 0.3125lessa), 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-lessa 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.
