The definition of a rod is as follows:
A rod is a unit of length, equal to 11 cubits, 5.0292 metres or 16.5 feet. A rod is the same length as a perch[1] and a pole. The lengths of the perch (one rod) and chain (four rods) were standardized in 1607 by Edmund Gunter.
The length is equal to the standardized length of the ox goad used by medieval English ploughmen; fields were measured in acres which were one chain (four rods) by one furlong (in the United Kingdom, ten chains).

The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length defined to be exactly equal to 149,597,870,700 metres. Historically, the astronomical unit was conceived as the average Earth-Sun distance (the average of Earth's aphelion and perihelion), before its modern redefinition.
The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
