What Is Square Pole?
A square pole is an old unit used to measure land area. It shows how much ground a piece of land covers, like the size of a small part of a field or garden. It is the same as a square rod or a square perch.
People used square poles mainly in farm and land surveys to describe the size of plots before metric units became common.
Definition
A square pole is the area of a square whose sides are one pole long. A pole is a unit of length that is the same as a rod or a perch.
One pole in length is:
- 5.5 yards
- 16.5 feet
- 5.0292 meters (about)
So one square pole has an area of:
- 30.25 square yards
- 272.25 square feet
- About 25.29 square meters
In land measure one square pole is also exactly:
- 1 160 of an acre
- 0.0025 acre
History / Origin
The square pole comes from old English land measuring systems. Long ago, farmers and surveyors used simple tools and easy fractions to divide land for taxes, rent and farming.
The basic length was the pole, also called a rod or perch. A square built from this length on each side became a square pole. Many square poles made a larger unit called an acre.
This system was used across England, Ireland and later in many parts of the British Empire. Over time, governments moved to clearer systems like metric units, but the old names stayed in old documents.

There is no single worldwide symbol for square pole, but several forms are commonly seen, especially in old papers:

All of these usually mean exactly the same unit of area.
