Common Perches to Acres Conversions

Historical Background

The perch as a unit of measurement dates back to medieval England. The name comes from the Latin "pertica," referring to a measuring rod. Surveyors would use a wooden or metal rod exactly 16.5 feet (1 rod/perch/pole) long to measure land.

The perch became standardized during the reign of King Edward I in the 13th century. The system was designed around practical agricultural needs: a furlong (660 feet) was the length a team of oxen could plow without resting, and an acre was the amount of land that could be plowed in a day.

Understanding Roods

A rood is another traditional land measurement unit equal to 40 perches or 1/4 acre. The term "rood" is less common today but still appears in historical documents. Understanding roods can help when interpreting old property descriptions that use mixed units.
