The rod is useful as a unit of length because integer multiples of it can form one acre of square measure (area). The 'perfect acre' [2] is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square ...
Rood is an English unit of area equal to one quarter of an acre [2] or 10,890 square feet, exactly 1,011.7141056 m 2. A rectangle that is one furlong (i.e., 10 chains , or 40 rods) in length and one rod in width is one rood in area, as is any space comprising 40 perches (a perch being one square rod).

The Rhynland rood (Rijnlandse roede) was a standard Dutch measurement. It was changed in 1859 to the "Cape Foot" due to a drift in standards. 1 Rhynland foot (Rijnlandse voet) = 12 Rhynland inches (Rijnlandse duim) = 1.030 English feet. 1 Rhynland rood = 12 Rhynland feet = 12.36 (≈12.4) English feet. 1 Cape foot = 1.033 English feet.
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
In other references the furlong and the rood appear to be units related to ploughing procedures. Of particular interest was the rood which was 15 North German feet in length, the North German foot being equivalent to 335 mm (13.2 inches). [3]: 50 Craftsmen, on the other hand used a shorter Roman foot.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
