Confusion results in western terms between “rod” and “rood” and apparently at one time “rod” was a unit of brick wall with a method to “estimate the value of a rod of brickwork…” (p. 742) and the measures of “roods” of “superficies…as under”

  • 144 sq. inches are equal to 1 square foot
  • 9 square feet………………….1 square yard
  • 2 7/9 square yards………….1 square pace
  • 10-89 square paces…………1 square pole
  • 40 square poles………………1 square rood
  • 4 square roods……………….1 square acre

Followed by very large surfaces, as of countries, are expressed in “square miles” which is shown in conversion as multiples of units of “Square feet”;”Square yards”;”Square poles”;”Square Roods”;”Square Acres”. This leads to the comment above that “Perhaps the only standard that can be safely referred to at the present day is that belonging to the Royal Astronomical Society.”!
p. 1224 – From “The Encyclopedia of Architecture – Historical, Theoretical, and Practical -The Classic 1867 Edition” Joseph Gwilt c) 1982 Crown Publishers, Inc.
