How to convert Acre to Killa
To convert acre to killa, multiply the number of acre by the conversion factor 1, because 1 ac = 1 killa. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 killa = 1 ac, so you divide by 1 (or multiply by 1) to turn killa back into acre.
killa = ac × 1 ·
ac = killa × 1
- Write down the value you want to convert, in acre.

Acre vs Killa: which is bigger?
A acre is the larger unit: one acre equals 1 killa. Put another way, you need 1 killas to make a single acre.
What is a Acre? History, origin and usage
Ac is simply the abbreviation for the acre, one of the oldest English land measures, whose name comes through Norman French from a root meaning 'cultivated field'. It was historically the area a team of eight oxen could plough in a day, fixed as one chain by one furlong.
The acre remains a statutory unit in the United States and across the Commonwealth, and is a main unit for Indian agricultural land alongside the bigha and hectare. It is used for farms, estates and large plots worldwide.
One acre is 4,840 square yards or 43,560 square feet, about 0.405 hectare, and roughly nine-tenths the size of an American football field. It equals 8 kanal or 160 marla in the Punjab system.
What is a Killa? History, origin and usage
Killa is the colloquial Punjab and Haryana name for an acre, and is synonymous with the ghumaon, an older term for land that a pair of oxen could plough. Its prominence grew through the killabandi system of British canal-colony settlement, in which large blocks were squared off and divided into one-acre killas.
Farmers and revenue records in Punjab, Haryana and parts of Rajasthan and Himachal Pradesh routinely measure agricultural holdings in killa. One killa is treated as one acre for all practical purposes.
One killa equals one acre, which is 8 kanal or 160 marla, and 25 killa make one murabba. The grid of square killas you see in Punjab's farmland is a direct legacy of the killabandi land consolidation.

Tips for converting Acre to Killa
- To go from acre to killa, multiply by 1; to go back, divide by 1 (or multiply by 1).
- For a quick mental estimate, remember that 1 acre ≈ 1 killa, so 10 acre ≈ 10 killa.
- 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 Acre to Killa converter
Type a number into the Acre field and the equivalent in Killa 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 Killa field to convert the other way (killa to acre). 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 ac = 1 killa), 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 acre-to-killa conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
