Dealing with boundary disputes involves reading legal documents, many of which date back to long before the introduction of decimal units. As such, if a reference is made to the length of a boundary, it is more often than not, specified in terms of feet and yards. This is straight forward as most people know what an inch is, and many will know that there are 25.4mm to the inch.  Most people will also know that there are 12 inches to a 1 foot and 3 feet to a yard etc. It is not a difficult task to convert these imperial dimensions into the metric units.

However, what about units of area? It is not uncommon to hear people refer to land area in terms of Acres. But have you heard of  a Rood? or a Perch? On several occasions now I have been reading a conveyance and come across these terms. But what are they?

I had to use that wonderful resource ‘Google’ to find some answers. On a website I found some useful answers …… and some information that made things more confusing.

The Rood

Generally the Rood was considered to be an area of 1210 square yards. Which is equivalent to a quarter of an Acre.

The Perch

This is a confusing measurement. On the website mentioned above, the Perch is a unit of length, whereas the in the conveyance I was reading it is a unit of area. It is sometimes referred to as a ‘Rod’ or ‘Pole’.  It is commonly considered to be 5 1/2 yards long or 16 1/2 feet and used mainly in relation to land. In some instances the ‘Square Perch’ was referred to a Perch.

This is one of the reasons I enjoy working with boundaries. They are endlessly fascinating and not ‘run-of-the-mill’ surveying.
