How to convert Gaj to Chatak
To convert gaj to chatak, multiply the number of gaj by the conversion factor 0.2, because 1 gaj = 0.2 chatak. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 chatak = 5 gaj, so you divide by 0.2 (or multiply by 5) to turn chatak back into gaj.
chatak = gaj × 0.2 ·
gaj = chatak × 5
- Write down the value you want to convert, in gaj.
- Multiply it by 0.2.
- The result is the same area/length/quantity expressed in chatak.

Gaj vs Chatak: which is bigger?
A chatak is the larger unit: one chatak equals 5 gajs. Put another way, you need 5 gajs to make a single chatak.
What is a Gaj? History, origin and usage
As a land unit the gaj is simply a square gaj, the gaj (or gaz) being the South Asian yard. The word descends from the Classical Persian gaz, a yard-like length carried into Hindustani during the Mughal era, when Emperor Akbar standardised an Ilahi gaz of about 33 inches around 1584. It is unrelated to the identical-sounding Hindi word gaj meaning elephant.
Gaj is the everyday unit for plots, houses and carpet area across North India, especially Delhi, Uttar Pradesh, Haryana, Punjab and Rajasthan, where listings routinely quote a plot as so many gaj. It is functionally the square yard, so it sits between the square foot and larger units like the bigha or acre.
One gaj equals one square yard, which is nine square feet, so a 100-gaj plot is 900 square feet. The same word for the linear yard also gives Indian roads their old milestone measurements.
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.

Tips for converting Gaj to Chatak
- To go from gaj to chatak, multiply by 0.2; to go back, divide by 0.2 (or multiply by 5).
- For a quick mental estimate, remember that 1 gaj ≈ 0.2 chatak, so 10 gaj ≈ 2 chatak.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Gaj to Chatak converter
Type a number into the Gaj 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 gaj). 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 gaj = 0.2 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 gaj-to-chatak conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
