How to convert Acre to Square Perch
To convert acre to square perch, multiply the number of acre by the conversion factor 160, because 1 ac = 160 perch². The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 perch² = 0.00625 ac, so you divide by 160 (or multiply by 0.00625) to turn square perch back into acre.
perch² = ac × 160 ·
ac = perch² × 0.00625
- Write down the value you want to convert, in acre.
- Multiply it by 160.
- The result is the same area/length/quantity expressed in square perch.

Acre vs Square Perch: which is bigger?
A acre is the larger unit: one acre equals 160 square perchs. Put another way, you need 160 square perchs to make a single acre.
What is a Acre? History, origin and usage
The acre is one of the oldest English land measures, its name coming through Norman French from a Germanic root meaning 'cultivated field' (compare German Acker and Latin ager). Historically it was the area a team of eight oxen could plough in a single day, formalised as one chain by one furlong (66 by 660 feet).
It remains a statutory land unit in the United States and across many Commonwealth countries, and in India it is one of the main units for 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 is roughly nine-tenths the size of an American football field. The furlong in its definition literally means a 'furrow long', the distance oxen ploughed before resting.
What is a Square Perch? History, origin and usage
A square perch is 1/160 of an acre — 30.25 square yards (272.25 sq ft). Also called a square rod or square pole, it is the smallest of the three units in "acres, roods and perches", and 40 of them make one rood.

Tips for converting Acre to Square Perch
- To go from acre to square perch, multiply by 160; to go back, divide by 160 (or multiply by 0.00625).
- For a quick mental estimate, remember that 1 acre ≈ 160 square perch, so 10 acre ≈ 1,600 square perch.
- 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 Square Perch converter
Type a number into the Acre field and the equivalent in Square Perch 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 Perch field to convert the other way (square perch 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 = 160 perch²), 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-square perch conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
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.
