SponsoredThis converter turns perches into acres (perch to acre). Enter a value and the result updates as you type. 1 perch equals exactly 0.00625 acres.
There are 160 perches in an acre, so perches divide by 160. A perch is the same as a square rod, a square 16.5 feet on each side, which is 272.25 square feet. Land is still measured in perches in Sri Lanka, and older land titles in Australia use acres, roods and perches.
The result is rounded to 6 decimal places, but the factor behind it never is, so long chains of conversions stay accurate. You can type decimals, thousands separators or fractions such as 2 1/2, and the conversion table below lists common values.

Perch, Rood and Acre
Sri Lanka's Survey Department converts land areas as acres, roods and perches: 1 acre is 4 roods, and 1 rood is 40 perches. NIST defines the rod, pole or perch as a length of 16.5 feet and the square rod as 272.25 square feet, 25.29285264 square meters.
| Unit | Perches | Square Feet |
|---|---|---|
| 1 perch | 1 perch | 272.25 ft² |
| 1 rood | 40 perches | 10,890 ft² |
| 1 acre | 160 perches | 43,560 ft² |
A rood is an area, a quarter acre; a rod is a length. Some sites mix them up and write that 40 perches make a rod. A Gunter's chain is 66 feet, 4 rods or 100 links, and an acre is 10 square chains. The Feet Converter turns rods and chains into other lengths, and the Fence Perimeter Calculator measures the boundary.

In 1885 Queensland's parliament debated the Undue Subdivision of Land Prevention Bill, whose clause 9 barred registering suburban or country allotments of less than sixteen perches, according to the Queensland Hansard. Sixteen perches is a tenth of an acre, about 404.69 square meters.
