A rod is equal to 5.0292 meters, 11 cubits or 16.5 feet. It is also equal to a pole and a perch, two other units of length.
Edmund Gunter standardized the chain and the perch, which is equal in length to a rod, as units of measurement for length in 1607. Specialized fields use the rod as a unit of measurement, but it is not common in general math. One example, is the recreational canoeing industry using the rod to measure because the length of a rod is approximately the length of a standard canoe in the United States.
