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.
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.

How to use this Square Perch to Acre converter
Type a number into the Square Perch field and the equivalent in Acre 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 Acre field to convert the other way (acre to square perch). 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 perch² = 0.00625 ac), 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 square perch-to-acre 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.
