Acre vs Guntha: which is bigger?
A acre is the larger unit: one acre equals 40 gunthas. Put another way, you need 40 gunthas 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 Guntha? History, origin and usage
The guntha (also spelt gunta) is a traditional unit of western and southern India defined as one-fortieth of an acre. It is most often visualised as a square of about 33 feet by 33 feet, giving roughly 1,089 square feet.
It is the standard sub-acre unit in Maharashtra, Karnataka, Andhra Pradesh and Telangana, used for farmland and plots in revenue records and property deals. Holdings are commonly described as a number of acres and gunthas.
Forty guntha make one acre. The unit's near-square shape of about 33 by 33 feet makes it easy to picture as a single small field plot.

Tips for converting Acre to Guntha
- To go from acre to guntha, multiply by 40; to go back, divide by 40 (or multiply by 0.025).
- For a quick mental estimate, remember that 1 acre ≈ 40 guntha, so 10 acre ≈ 400 guntha.
- 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 Guntha converter
Type a number into the Acre field and the equivalent in Guntha 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 Guntha field to convert the other way (guntha 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 = 40 guntha), 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-guntha conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
