About the rood

A rood is a strip one furlong (660 ft) long and one rod (16.5 ft) wide, which is exactly a quarter of an acre: 40 perches, 1,210 sq yd or 10,890 sq ft, about 1,011.71 m².

Many older English, Irish and colonial deeds write areas in three parts, such as “2a 1r 20p” for 2 acres, 1 rood and 20 perches. To convert, turn each part into square feet (43,560 per acre, 10,890 per rood, 272.25 per perch) and add them up.
